INTRODUCTION ---------------------------------------------------------

Portal is a Half-Life 2 engine game designed as a showcase for aninnovative game mechanic: the portal gun. Portal is available atretail as part of the "Orange Box" compilation, or it can also bebought on its own from Steam for US$19.99.

Portal is actually an updated version of an older game called"Narbacular Drop", which is available for free. Narbacular Drop has

far fewer levels, and much worse graphics, and some exploits thatwork in Narbacular Drop don't work in portal.

PORTALS. If you don't get these, you're going to be in trouble.There are two, the blue portal and the yellow portal. Go through theblue portal and you come out of the yellow portal, and vice versa.If only one of the portals is active, it'll be all cloudy indicatingthat it can't be used because it has no other end. The two portalsexist in exactly the same map - there's no "multi-dimensional" thing

going on. There are all kinds of funky things to learn about portals,but you'll learn most of them by playing the game, so I won't explainthem here.

METAL. Walls and floors can be made out of it. If they are, youcan't put portals on them. Bummer.

BUTTONS. All buttons are red. Some buttons are small, and you canpress them yourself with the USE key, whereupon they'll activatesomething. Usually, the button will reset after a while and the

thing it activated will shut down. Other button are large, and youcan activate them by standing on them, but usually this will be nouse because you will need to be somewhere else to interact with thething the button's connected to. The solution is to pick up a..

CUBE. Handy little things which you drop on big buttons to hold themdown. You can use them for other purposes too. Cubes can bedestroyed. If a cube is destroyed, you'll usually be given anotherone at the point where you collected the cube from originally.

EMITTERS, PELLETS, RECIEVERS. Emitters occasionally shoot energypellets. If an energy pellet hits a reciever, it activates something

(permanently). If an energy pellet hits you, you die. If an energypellet hits anything else (such as a wall, or a cube) it bounces off,and will continue bouncing for a finite time before it explodes. Theemitters are very waste-conscious; they will not shoot another energypellet while one is already in the air (but if there are two emitters,each one can have a pellet in the air) and they will stop shootingaltogether when all tasks requiring energy on a map have beencompleted.

KILLER FLOOR. Also known as goo. It's on the floor. It kills you.Any questions?

TURRETS. Ok, I'll be a bit less facetious about these guys, since

they're quite interesting. Essentially, they sit there looking inone direction (you can see their red scan beam emitted in thatdirection, but their field of vision is actually about a 45 degreecone with the beam in the centre). If they see you, they activateand start shooting you with their machine guns. Glass, walls, orcubes will block the guns (glass will be cracked, but won't break).They continue firing until you're dead or you move out of the way.Damage in Portal is a bit odd - essentially, if you get shot too muchyou're dead, but there is no LASTING damage. You can get shot alittle bit by every turret on a map and you'll live, but if one ofthem shoots you too much, you'll die. Assuming you move out of theway, they'll search for you for a moment, then shut back down again.And they have cool sing-song computer voices and they'remagnificiently creepy. How do you defeat them? It's actually easy.You just push them over (!) from the side. You can also drop theminto portals if you like - anything that makes them fall over. Theonly kicker is that when they are shooting you, their shots knock youback, so you can't simply approach them and tip them from the front.But since you have portals, approaching them from another directioncan't be too difficult, can it? By the way, turrets are smart andrecognise other turrets, so they won't start shooting when they seeone. But you CAN make them shoot at another turret by dodging outof the way carefully, and you CAN make them fall on each other.

ROCKET TURRETS. Not the same as the regular turrets. These guys

move through a full 360 degree fire arc, but they move reallyslowly. If they see you, they'll pause for a good second beforefiring a rocket at you. In that second, you want to get out of the

8/4/2019 Portal FAQ

way. Seriously. One rocket hit equals death. Rocket turrets cannotbe defeated or destroyed - even if you trick them into shootingthemselves, even a rocket hit does not kill them. They can, however,be mercilessly exploited, as we shall see.

THE CAKEGLADOS

PRELUDE --------------------------------------------------------------"Hello and again welcome to the Aparture Science Computer AidedEnrichment Centre. We hope your brief detention in the relaxationvault has been a pleasant one. Your specimen has been processed andwe are now ready to begin the test proper. Before we start, however,keep in mind that although fun and learning are the primary goals ofall Enrichment Centre activities, serious injuries may occur. Foryour own safety and the safety of others, please refrain from*static*.. and back. The portal will open in 3, 2, 1.."

[Note: the music you hear on the radio here is actually the endingsong, in a different form.]

1. Walk through the yellow portal and around the cell into the nextroom.

2. Pick up the cube and drop it on the button.

"Excellent. Please proceed into the chamber lock after completingeach test. First, however, note the incandescent particle fieldacross the exit. This Apature Science Material Emancipation gridwill vapourise any unauthorised equipment that passes through it; for

instance, the Apature Science Weighted Storage Cube."

3. Walk through and get in the lift.

TEST 1 ---------------------------------------------------------------"Please place the Weighted Storage Cube on the 15 hundred megawattAperture Science Heavy Duty Supercolliding Superbutton."

1. Fall down from the entrance platform and turn 180 degrees to findthe yellow portal. Wait for the yellow portal to change to the cube

chamber. Go through the yellow portal and pick up the cube, thenreturn through the blue portal (if it has disappeared, wait for it toreapper).

2. Wait for the yellow portal to change to the button chamber, thengo through the yellow portal and drop the cube on the button.

"Perfect. Please move quickly to the chamber lock as the effects ofprolonged exposure to the button are not part of this test."

3. Return through the blue portal, then wait for the yellow portalto change to the exit gate. Walk through and get in the lift.

TEST 2 ---------------------------------------------------------------"You're doing very well. Please be advised that a noticable taste ofblood is not part of any test protocol, but it is an unintended sideeffect of the Aperture Science Bacterial Emancipation Grid, which may,in semi-rare cases, emancipate dental fillings, crowns, enamel, andteeth."

1. Pass through the door and down the stairs, then wait for the blueportal (it may take a while). Pass through it and fall down, thenget the portal gun.

"Very good. You are now in possession of the Aperture Science

Handheld Portal Device. With it, you can create your own portals.These intradimensional gates have proven to be completely safe. TheDevice, however, has not. Do not touch the operational end of thedevice. Do not look directly at the operational end of the device.Do not submerge the device in liquid, even partially. Mostimportantly, under no circumstances should *static*."

2. Place the blue portal on any wall and walk through it to the exitdoor, then pass through and get in the lift.

TEST 3 ---------------------------------------------------------------"Please proceed to the chamber lock. Mind the gap."

* Shoot any portal onto the wall behind the security camera, whilethe other portal is open, to destroy the camera. You can destroy anycamera in the game this way. You don't ever have to do this, butdestroying them all gets you the Camera Shy achievement. From now onI will only mention the locations of security cameras.

1. Shoot a blue portal onto any wall and pass through it to cross thefirst gap.

2. Shoot a blue portal onto the wall across the second gap, then passthrough the yellow portal to cross the second gap. Get in the lift.

"Well done. Remember, the Aperture Science Bring your Daughter ToWork Day is the perfect time to have her tested."

TEST 4 ---------------------------------------------------------------"Welcome to Test Chamber 4. You're doing quite well."

* Security Camera. "To ensure the safe performance of all authorisedactivities, do not destroy vital testing apparatus."

1. Shoot a blue portal onto the floor underneath the cube dropper

(you can wait for a cube to fall first if you like and then aim underit).

2. Collect the cube from the yellow portal and drop it on the button.

"Once again, excellent work. As part of our required test protocol,we will not monitor the next test chamber. You will be entirely onyour own. Good luck."

* Security camera. "For your own safety, do not destroy vital testingapparatus."

3. Get in the lift.

2. Shoot the blue portal onto any wall and pass through. Get thecube and drop it onto one of the buttons.

3. Pass through the blue portal again onto the upper platform.

* Security camera on the wall to your right. "Certain objects may bevital to your success. Do not destroy testing apparatus."

4. Shoot the blue portal onto the wall behind the opposite platform,then pass through the yellow portal. Get the cube and drop it ontothe other button. Go through the opened gate.

"As part of a required test protocol, our previous statementsuggesting that we would not monitor this chamber was an outrightfabrication. Good job. As part of a required test protocol, we willstop enhancing the truth in 3... 2... *static*"

5. Shoot the blue portal onto any wall. Pass through and get in thelift.

TEST 6 ---------------------------------------------------------------"While safety is one of many Enrichment Centre goals, the ApertureScience High Energy Pellet seen to the left of the chamber can, andhas, caused permanent disabilities, such as vaporisation. Please becareful."

1. Shoot the blue portal onto the ceiling above the receptor. (Notethe yellow beam indicating a straight line to the receptor.)

"Unbelievable. You, subject name here, must be the pride of subjecthometown here."

8/4/2019 Portal FAQ

6/25

"Warning devices are required on all mobile equipment. However,alarms and flashing hazard lights have been found to agitate the HighEnergy Pellet and have therefore been disabled for your safety."

1. Shoot the blue portal onto the wall opposite the emitter. (Notethe burn mark on the wall where the energy pellet is hitting it.)

"Good. Now use the Aperture Science un-stationary scaffold to reachthe chamber lock."

2. When the moving platform is at the maximum left side, shoot theblue portal onto the ceiling above it, then drop through the yellowportal onto it (you can look through the portal to get your timingright). Ride the portal to the exit gate and get in the lift.

TEST 8 ---------------------------------------------------------------"Please note that we have added a consequence for failure. Anycontact with the chamber floor will result in an unsatisfactory markon your official testing record, followed by death. Good luck."

1. Wait for the yellow portal to open. Shoot the blue portal ontothe wall opposite the emitter (where the burn mark is).

2. Wait for the Pellet to pass through the portal. Once it ismoving from side to side in front of you, shoot the blue portal ontothe wall opposite the reciever (where the light is).

(If the pellet explodes halfway through, try again but be faster! :)

3. Shoot the blue portal onto the wall at the end of the platformwhere you are, and step through it onto the inner platform.

4. Shoot the blue portal onto the wall behind where the movingplatform stops, and step through the yellow platform onto it. Ridethe moving platform to the end and get in the lift.

"Very impressive. Please note that any appearance of danger ismerely a device to enhance your testing experience."

TEST 9 ---------------------------------------------------------------"The Enrichment Centre regrets to inform you that this next test isimpossible. Make no attempt to solve it. The Enrichment Centreapologises for this clearly broken test chamber. Once again, theEnrichment Centre offers its most sincere apology on the occasion ofthis unsolvable test environment. Frankly, this chamber was amistake. If we were you we would quit now."

1. Yea, right! Shoot the blue portal onto the floor underneath thecube. Let the cube fall through and then pass through yourself.

2. Shoot the blue portal through the hole in the wall above the forcefield to the distant side of the walled-off chamber, then pick upthe cube and walk through the yellow portal.

extreme pessimism."

TEST 10 --------------------------------------------------------------

8/4/2019 Portal FAQ

7/25

"Hello again. To reiterate *static* previous request *static* ofmomentum."

1. Wait for the yellow portal to appear on the wall above and behindyou, then shoot the floor with the blue portal and jump (don't justfall) in. Climb the stairs and enter the next room.

2. Wait for the yellow portal to appear on the wall above and behindyou, then shoot the floor at the bottom of the pit with the blueportal, jump, and fall all the way in. Once over the pit, enter thenext room.

"Spectacular. You appear to understand how a portal affects forwardmomentum, or to be more precise, how it does not."

3. Shoot the blue portal onto the wall above and behind you, thenjump and fall into the yellow portal. You should land on theplatform with a marker tile with 2 circles on it.

"Momentum, a function of mass and velocity, is conserved betweenportals. In layman's terms, speedy thing goes in, speedy thingcomes out."

4. Wait for the wall above where you previously were to move forward,then shoot the blue portal onto it and jump and fall again into theyellow portal. Get in the lift.

TEST 11 --------------------------------------------------------------"The Enrichment Centre promises to always a safe testing environment.In dangerous testing environments, the Enrichment Centre promises toalways provide useful advice. For instance: 'The floor here willkill you. Try to avoid it.'"

* Security Camera on the wall behind you as you come in. "Vitaltesting apparatus destroyed." (This is repeated for every camera fromnow on.)

1. Shoot the blue portal onto any wall. Wait for the portal tochange to a platform where it's safe to walk, then pass through andpress the red button. It opens a door on the opposite wall; quicklyshoot the blue portal through it onto the far wall of the chamberwithin.

2. Wait for the yellow portal to reappear behind you and pass throughit.

3. Look through the large window. When the yellow portal is about tobe opposite the reciever, shoot the blue portal opposite the emitterin this room (look for the burn mark). Remember to allow time for thepellet to get to the portal - shoot as early as you can.

4. Shoot the blue portal onto any wall. Wait for the portal tochange to the moving platform, then walk through and get on it. Ridethe moving platform to the centre of the room and get the upgradedportal gun.

"The Device has been modified so that it can now manufacture two

here."

5. Press the red button that appears when you get the upgraded portalgun, and shoot the blue portal through it at the far wall. Get backon the moving platform and ride it to the yellow portal, then passthrough. Get in the lift.

TEST 12 --------------------------------------------------------------"*static* fling yourself. *static* fling into spa- *static*."

1. Shoot a blue portal at the wall opposite you over the pit, and ayellow portal into the bottom of the pit. Jump and fall throughthe yellow portal and use momentum to reach the platform above youroriginal location, with a two-dot marker.

2. Shoot the blue portal onto the wall further above and furtherforward of the previous one, then repeat the jump and fall to landon the platform with a three-dot marker.

3. Shoot the blue portal onto the wall behind the red button, thatis angled at 45 degrees, and repeat the jump and fall through theyellow platform to land on the platform with a cube.

4. Get the cube, jump down (no need to portal) and put the cube onthe button.

5. Repeat the jump and fall to get back to the platform with thecube. Go through the exit gate and get in the lift.

"Wheeeeeeeeeeeeeeeeeeeeee *static*"

TEST 13 --------------------------------------------------------------

"Now that you are in control of both portals, this next test couldtake a very, very, long time. If you become light-headed from thirst,feel free to pass out. An intubation associate will be dispatched torevive you with peptic salve and adrenaline."

* Security camera on the wall behind you as you enter.

1. Shoot the yellow portal onto the wall on the upper floor, behindthe cube. Shoot the blue portal onto any wall near you. Passthrough, get the cube, fall down with it and put it on the button,then pass through again and go through the opened gate.

* Security camera on the wall behind you as you enter the larger halfof the chamber.

2. Shoot the blue portal onto the wall in front of the emitter andthe yellow portal onto the ceiling in line with the reciever. Waitfor a pellet to hit the reciever.

3. Shoot the blue portal onto the ceiling above the moving platformand the yellow platform onto any wall you can reach. Look throughthe portal to get your timing right to pass through and land on theplatform. Get the cube and fall back to the floor.

4. Shoot the blue portal onto the ceiling above the left-hand button

(the one with a one-dot marker above it). Look through the yellowportal to check your positioning. Once done, "post" the cube throughthe yellow portal (you can go through too if you like, but you don't

have to)

5. Shoot the blue portal through the high-up gate you came throughfrom the first chamber. Enter the yellow portal to go back to thefirst chamber. Shoot the blue portal onto any wall you can reach,then take the cube off the button and pass through the portal.

6. Shoot the blue portal onto the ceiling above the other button (theone with a two-dot marker above it). "Post" the cube through theyellow portal. The gate should open.

7. Shoot the blue portal onto the wall above the gate. Go throughthe yellow portal, go through the gate and get in the lift.

"As part of a previously mentioned required test protocol, we can nolonger lie to you. When the testing is over, you will be.. missed."

TEST 14 --------------------------------------------------------------"All subjects intending to handle high energy gamma leaking portal

technology must be informed that they may be informed of applicableregulatory compliance issues. No further compliance information isrequired or will be provided, and you are an excellent test subject."

1. As you enter the area, turn left and walk towards the pit. Aset of stairs will appear. Climb it.

2. Shoot the blue portal onto the wall opposite where the cube is.Wait for the staircase to disappear, then shoot the yellow portalonto the floor where it used to be, and jump from the upper platforminto the yellow portal to fling yourself to the cube.

3. Get the cube and put it on the button. Turn back and shoot the

yellow portal onto the ceiling above the reciever on the upperlevel.

4. Pass through the gate that the button opened and jump across themoving platforms (old school!) Once you get to the other side, shootthe blue portal onto the wall opposite the emitter and wait for thepellet to hit the reciever.

"Very, very, good. A complementary victory lift has been activatedin the main chamber."

5. Pass through the blue portal yourself (hey, why not!) to land onthe reciever (it does you no harm to land on an active reciever) thenwalk to the elevator platform in the main room and get in the lift.

TEST 15 --------------------------------------------------------------"The Enrichment Center is committed to the well-being of allparticipants. Cake, and grief counselling will be available at theconclusion of the test. Thank you for helping us help you help usall."


1. Shoot the blue portal onto the extruded wall above and behind youas you enter. Shoot the yellow portal onto the floor and jump into

it. As you fall, shoot the yellow portal onto the floor again atthe point where you are about to land. Keep doing this until you areflung through the force field. Move into the next room.

8/4/2019 Portal FAQ

10/25


2. Shoot the blue portal onto the wall opposite the emitter and theyellow portal onto the wall anywhere opposite the chamber with thereciever in it. Wait for the pellet to pass through the portal,and then quickly pass through the force field before the pellet

passes back through the portal. (Passing through a force fielddestroys all your portals.)

3. Quickly place the blue portal on the wall where the pellet hit(look for the burn mark) and the yellow portal on the ceiling abovethe reciever. Wait for the pellet to hit the reciever. Get onthe elevator platform and move to the next room.

4. Shoot the blue portal onto the extruded wall above and behind youas you enter. Facing in the direction that you entered, turn left andpass through an arch into a small sub-chamber.

* Security camera on the left hand side of the sub-chamber.

5. Shoot the yellow portal onto the bottom of the pit in the sub-chamber. Jump and fall through and, just as in step 1, shoot theyellow portal onto the floor again when you are just about to land.Keep trying steps 4-5 until you are flung through the force field.

6. In the new area repeat the same process as in step 1 to getthrough the force field. Take care not to drift to the side or youmay hit the energy pellet.

7. Shoot the blue portal onto the wall that the energy pellet ishitting AFTER it's bounced off the 45 degree angled wall. Shoot the

yellow portal onto the flat wall opposite on the other side of theangled wall. Wait for the pellet to hit the reciever.

8. Repeat the step 1 process *AGAIN* to get back through the forcefield.

9. Pass through the arch in this area and use portals to cross thebackwards moving platforms over the killer floor. Use the followingprocedure: shoot the blue portal onto the wall facing you at the firstcorner of the passage. Then shoot the yellow portal onto the outsidewall, wait for there to be a platform behind the portal and stepthrough. Quickly turn and shoot the blue portal at the facing wall ofthe second corner of the passage and ride the platform back to theoutside. Again wait for there to be a platform behind the yellowportal and pass through. Now you should be able to see the room atthe other end, shoot the blue portal into the room, but do not shootdirectly forward as a metal portal-proof pillar there blocks you -shoot to the side of the pillar. Then shoot the yellow portal ontoany wall in the passage and pass through it.

* Security camera, probably opposite you.

10. Ride the elevator platform in the far right corner of the roomup into the chamber there. Shoot the blue portal onto one of thewalls of the chamber. Look across the room at the high-up chamber

in the opposite corner and shoot the yellow portal there.

11. Very quickly press the red button in the chamber you're in,

8/4/2019 Portal FAQ

11/25

rush through the blue portal, press the red button in the chamberyou arrive in, then from the window of the chamber shoot the blueportal in front of the emitter and the orange portal in front ofthe reciever. Wait for the pellet to hit the reciever. Get onthe elevator platform and get in the lift. Phew!

"Did you know, you can donate one or all of your vital organs to the

Aperture Science Self-Esteem Fund for Girls? It's true."

TEST 16 --------------------------------------------------------------"Due to mandatory scheduled maintenance, the appropriate chamber forthis testing sequence is currently unavailable. It has been replacedwith a live fire course designed for military androids. TheEnrichment Centre apologises for the inconvenience and wishes you thebest of luck."

* Security camera right in front of you as you round the corner.

1. Push over the turret facing to the left in the first area.

* Security camera right in front of you as you round the corridorcorner.

2. Facing the left-hand arch, quickly enter the beam and shoot theblue portal onto the wall behind the turret. Move quickly out ofthe archway before the turret fires. Shoot the yellow portal ontoany wall, pass through and push the turret over.

3. Repeat the same procedure with the turret in the alcove on theleft hand side of the corridor. This turret is quicker to fire so itmay get you once or twice, but you can still shoot a portal behindit, then use the opposite portal on any wall to get behind it and

push it over.

* Security camera above the turret in the alcove.

4. Hide behind the glass to prevent the next turret shooting you, andmove until it shuts down. Then quickly step in front of the glass andshoot the blue portal onto the ceiling above the turret (note the"X"). Again the turret may tag you, don't worry. Shoot the yellowportal onto the floor. Pick up one of the cubes and drop it throughthe yellow portal to smack the turret on the head. DO NOT GO THROUGHTHE PORTAL YOURSELF or the second turret, opposite, will shred you.

5. Hug the wall very closely to shoot the blue portal onto theceiling above the second turret (notice another red X). Drop thesecond cube through the yellow portal and brain the turret.

* Having moved the two cubes, you can move into the "secret" areathey were obstructing to see interesting things. Were those cubeseven supposed to be here, and part of the test?

6. Once you are sure the turret's dead, pass through the yellow portalyourself, and land behind the cube, further into the corner. Crouchand push the cube forward, hiding behind it to avoid the next turret'sfire. Shoot the blue portal behind the turrets, then hide behind thecube and make a quick sprint across the opening back to an area with

a portal-able floor. Shoot the yellow portal onto the floor, and falldown. Push over the two turrets.

7. Carefully move across to the side nearest you of the furthest door,and shoot the yellow portal onto the X on the ceiling above thecorner turret, then hide behind the frame before it shoots you.Quickly run across the door, then shoot a blue portal UNDERNEATH thenearest turret to the door. Enjoy the hilarious dialog as the turretskill each other ("Aaaaargh! It's me! My fault!") and rack up yourFriendly Fire achievement.

(Also, in this room, if you move carefully before killing any of theturrets, you can make the turret in the far right corner shoot theturret near the entrance, which makes it shriek "Don't shoot!" :) )

8. Just for a laugh, let's do it again. Enter the room and move tothe right, using the corner to hide from the turret in the far rightcorner. Shoot the yellow portal onto the X above it. Now, go tothe room next door and get a cube to drop on the button and open theexit gate (drop the cube quickly to avoid getting shot). You'll seethe tell-tale line that says there's another turret beyond the gate.Again use the room's internal corner to hide from the turret as you

move up to the exit gate and shoot the blue portal through thegauze wall underneath the turret in the next room. Whack!

* Security camera above where the third turret was.

9. Shoot the yellow portal at any safe wall and pass through.

* Security camera on the wall of the chamber where the turret was.

10. Shoot the yellow portal at the wall by the side of the turret inthe next chamber. Move to the side of the grille to see the sidewall. Shoot the blue portal at any safe wall, pass through, push theturret over and get in the lift.

"Well done, android. The Enrichment Centre once again reminds youthat android hell is a real place where you will be sent at the firstsign of defiance."

TEST 17 --------------------------------------------------------------"The Vital Apparatus Stand will deliver a Weighted Companion Cube in3.. 2.. 1.."

1. Pick up the cube.

"This Weighted Companion Cube will accompany you through the testchamber. Please take care of it."

2. Use the cube to climb the stairs in the next room. Drop it on thefloor, jump on it, jump up onto a stair, then look down from the stairand pick the cube up. Repeat this to climb two stairs.

3. Pick up the cube and hold it in front of you as you move down thetight corridor. It should deflect any energy pellets fired at you bythe emitter at the end, although you can crouch behind it to be sure.For future reference, this corridor is corridor A.

"The symptoms most commonly produced by Enrichment Centre testing aresuperstition, percieving inanimate objects as alive, and

hallucinations. The Enrichment Centre reminds you that the WeightedCompanion Cube will never threaten to stab you and, in fact, cannotspeak."

4. Keep holding the cube towards the emitters as you enter the nextroom. Wait for the right hand emitter in front of you to actuallyemit a pellet, and then quickly run backwards up the staircaseopposite it to block the pellet with your Cube. Walk backwards downthe corridor, holding the cube in front of you. (Don't just enter thecorridor without waiting for a pellet to be emitted first, because

there may already be a pellet in the corridor that will hit you in theback. If you go down holding the cube forwards, the active pellet mayexpire while you are in the corridor and you will be shot in the backby the emitter.) This corridor is corridor B.

* Security camera on the wall behind you at the end of this corridor.

5. Fall down from the high platform in the next room. There is apushed-out wall just behind you as you fall. Use portals to enterit to find a rather disturbing secret area.

6. Leave the secret area and enter the archway on your left, holding

the Cube. Use the cube to deflect the Pellet into the reciever.

* Security camera above the archway.

7. Use portals to return to the upper ledge where you entered theroom, and shoot the blue portal onto the wall tilted 45 degrees,opposite the reciever. Shoot the yellow portal onto the wall at theend of corridor B, to capture the pellet that was trying to kill youearlier. Wait for the pellet to hit the reciever.

"The Enrichment Centre reminds you that the Weighted Companion Cubecannot speak. In the event that the Weighted Companion Cube DOESspeak, the Enrichment Centre urges you to disregard its advice."

8. Walk back to corridor A, and shoot the blue portal onto the veryend of the corridor (you can do this without entering the corridor),again to capture the pellet. Shoot the yellow portal somewhereharmless to keep the pellet out of the way.

9. Return to the main area and shoot the yellow portal onto thepushed out wall (where the secret area was). Get the Cube. Carefullyenter the archway opposite the portal (watch out for the pellet).Walk to the raised button at the back of the wall and put the cube onit, then CAREFULLY stand yourself on the button at the front of theroom (there is JUST enough space for you to stand on the buttonwithout the pellet hitting you as it passes). Let the pellet hit thereciever.

10. Use portals to return to the platform where you came in, makingsure to take the cube with you. Jump across the three newly-raisedplatforms, turn right, and jump into the new section. Drop theCube on the button.

"You did it. The Weighted Companion Cube certainly brought you goodluck. However, it cannot accompany you for the rest of the test and,unfortunately, must be euthanised. Please escort your Companion Cubeto the Aperture Science Emergency Intelligence Incinerator."

11. Enter the next area, pass through the open gate and press thebutton to open the incinerator.

"Rest assured that an independant panel of ethicists has absolved theEnrichment Centre, Aperture Science employees, and all test subjectsof any moral responsibility for the Companion Cube euthanisingprocess."

(The following five quotes are repeated until the cube is destroyed)

"While it has been a faithful companion, your Companion Cube cannotaccompany you through the rest of the test. If it could talk (andthe Enrichment Centre takes this opportunity to remind you that itcannot), it would tell you to go on without it because it would ratherdie in fire than become a burden to you."

"Testing cannot continue until your Companion Cube has beenincinerated."

"Although the euthanising process is remarkably painful, eight out often Aperture Science engineers believe that the Companion Cube ismost likely incapable of feeling much pain."

"The Companion Cube cannot continue through the testing. State andLocal Statutory regulations prohibit it from simply remaining here,alone and companionless. You must euthanise it."

"Destroy your Companion Cube or the testing cannot continue."

12. Sorry... go get the Cube off the button and drop it into theincinerator. Get in the lift. (Not in cruelty, nor in wrath, thereaper came today; an angel visited this gray path, and took the cubeaway...) At least, you get your Fratricide achievement for this.

"You euthanised your faithful Companion Cube more quickly than any

test subject on record. Congratulations."

TEST 18 --------------------------------------------------------------"The experiment is nearing its conclusion. The Enrichment Centre isrequired to remind you that you will be baked, and then there will becake."

1. Place the blue portal on the ceiling opposite the pit and theyellow portal on any safe wall, and pass through it.

2. Crouch under the left-hand wall to look around another secretarea.

3. Leaving the secret area, place a blue portal on the highest andmost distant ceiling and the yellow portal on the wall on the oppositeside of the pit, slightly below you. Jump across the pit and into theyellow portal.

4. Shoot the blue portal on the ceiling above the three-dot platformand the yellow portal onto the floor, then fall through.

5. Repeat the same process to reach the four-dot platform, exceptthis time shoot the blue portal onto the wall above it.

6. Use the "fling" technique to reach the opposite platform. Shoot

the blue portal onto the pushed-out wall above you, the yellow portalonto the platform below you as you look over the edge of the platformyou're on, then jump and fall into the yellow portal.

8/4/2019 Portal FAQ

15/25

7. Press the red button in this chamber and pass through the openedwall.

8. Destroy the four turrets in this room by using the portals toredirect the energy pellets to hit them. The pellet emitter in thecentre of the room rotates between four directions firing a pellet

each time. It can be difficult to line up the portals with theturrets, so you'll just have to use trial and error, I'm afraid.

9. Shoot the blue portal onto one of the burn marks where thelaunched pellets are hitting the wall, and the yellow portal onto theextruded wall at the far end of the chamber. Wait for a pellet topass through the blue portal and then VERY QUICKLY shoot the blueportal onto the 90-degree rotated wall on the left hand side, thenshoot the yellow portal onto a safe wall, and jump through the yellowportal to hit the raised button. The aim here is to press the button(thus opening the door to the reciever) just before the pellet arrivesat the reciever, because the door does not stay open very long.

10. Get on the moving platform and ride across to the other side ofthe room. The jump to the platform with the cube on it is impossiblefrom here, so just jump and fall into the lower area. Shoot the blueportal onto any safe wall on the side where you started EXCEPT themoving wall section you came in by (look for the blue connecting line)and the yellow portal onto any safe wall in the current chamber.Press the button to make the wall you came in by re-open, then quicklyhead through the yellow portal to the other side. Once the openingwall turns 45 degrees, place the blue portal on it, then head to theright hand side of the platform you're on and place the yellow portalon the safe floor below, then jump into the yellow portal to "fling"yourself from the 45 degree angled wall and into the cube chamber.

11. Get the cube. Wait for the moving platform, jump onto it, andleave the cube on it. Fall back down into the lower chamber, shootthe blue portal over to the other side of the room again (again, noton the section you came in by) and place the yellow portal in thelower chamber. Pass through the yellow portal and collect the cubeoff the platform, placing it securely on the platform you're on.Pass back through the blue portal, press the button to open the wall,then return through the yellow portal, get the cube, and carry itback through the open wall. Drop it on the button.

12. Use portals to get back to the platform with the exit gate. Shootthe blue portal onto the wall above the exit gate, fall down onto theplatform in front of and below you then shoot the yellow portal ontothe floor and pass through. (Don't fall all the way down through theyellow portal, as you DON'T want a fling this time!)

13. Pass through the exit gate and down the corridor. No, it's notthe end.

* But you do get to blow up a security camera (right wall). So that'snice.

14. Ok, this bit is hard, but fun. Shoot the blue portal onto theonly platform that you can see above the killer floor. To the left of

where you came in is a deep pit; shoot the yellow portal there andthen jump down into it. You should bounce up through the blue portal,into the air. As you bounce up you will be able to see the surface of

8/4/2019 Portal FAQ

16/25

the next highest platform; shoot the yellow portal onto it. You willfall back down into the blue portal and be launched out of the yellowportal on the higher platform, from where you should be able to seethe surface of the next platform in the sequence; shoot the blueportal onto it, then fall back down into the yellow portal, and keepclimbing this way, alternating portals. If you miss one, just allowyourself to fall back into the portal you came from, bounce up and

down again, and then give it another try - but DO NOT TOUCH THEDIRECTION KEYS; if you miss falling into a portal, you're stuck.There are several platforms followed by a 45 degree angled flingplatform to climb up in this way. If it becomes difficult to keeptrack of what's going on while the screen is spinning wildly, bear inmind that the screen spinning does not affect the actual of yourmouse. In other words, line up your crosshairs as far as you can,then when the screen starts to spin take your hand off the mouse, waitto fall and bounce back through the portal, and your crosshairs willbe back in the same position they were before and you can carry onlining up.

15. Get in the lift.

"Well done. Be advised that the next test requires exposure touninsulated electrical parts that may be dangerous under certainconditions. For more information, please attend an Enrichment CentreElectrical Safety seminar."

TEST 19 --------------------------------------------------------------"Welcome to the final test. When you are done, you will drop theDevice in the Equipment Recovery Annex. Enrichment Centre regulationsrequire both hands to be empty before any cake *static* ake.."

* Security camera on your right as you round the corner.

1. Shoot a yellow portal onto the 45-degree angled wall below theemitter, and a blue portal onto the 45-degree angled wall below thereciever. Let a pellet pass through. Once it passes through theportal, shoot the blue portal somewhere else (out of the way of thepellet) so that when the pellet bounces back off the portal-proofwall, it hits the 45-degree angle in the normal way and isreflected into the reciever.

2. Notice that, at the corner of the moving platform's "track" thereis a platform and a portalable wall. Shoot the blue portal ontothe wall behind that platform, then the yellow platform onto anysafe wall, and pass through it. Looking beyond the corner along thetrack there is a door in the way, but you can shoot the wall of analcove on the left; shoot the yellow portal there and pass throughthe blue portal.

* Security camera above the switch in the alcove.

3. Hit the switch in the alcove and quickly shoot the blue portalonto the side wall beyond the door. Look through the yellow portaland wait for the platform to arrive, then jump on the platformthrough the portal.

4. Shoot the yellow portal onto the wall where the trapped pellet is

bouncing back and forth, and after it passes through, shoot theyellow portal somewhere else (behind/above you) to get the pellet outof the way.

8/4/2019 Portal FAQ

17/25

* Security camera on the corner of the platform's track.

5. Shoot the blue portal onto the side wall beyond the blocking wallon the platform track, then shoot the yellow portal onto the blockingwall. Very carefully jump through the yellow portal so that you arestanding "in" the blocking wall, then wait for the platform and jump

onto it. You will now see the cake symbol on the wall, and theplatform will round the final corner.. straight into an incinerator.

"Congratulations. The test is now over. All aperture technologiesremain safely operational up to 4000 degrees Kelvin. Rest assuredthat there is absolutely no chance of a dangerous equipmentmalfunction prior to your victory candescence. Thank you forparticipating in this Aperture Science Computer Aided Activity.Goodbye."

THE CAKE -------------------------------------------------------------1. Well, of course, you're not jumping in the stupid fire. Shoot

the blue portal above the platform over the fire, then the yellowportal on the side wall, and jump through.

"What are you doing? Stop it! I-i-i-i-i-i-i-ii...eee are pleasedthat you made it through the final challenge where we pretended wewere going to murder you. We are very, very happy for your success.We are throwing a party in honour of your tremendous success. Placethe device on the ground, then lie on your stomach with your arms atyour sides. A Party Associate will arrive shortly to collect you foryour party. Make no further attempt to leave the testing area.Assume the Party Escort Submission position or you will miss theparty."

2. On the higher platform, look back at the way you just came andyou'll see an entrance at the top. You need to fling yourself there.Place the blue portal on the very top of the back wall of the platformyou're on, then place the yellow portal on the floor, fall through it,and as you fall shoot the yellow portal where you are about to land.This should fling you into the upper chamber.

3. Walking down the corridor here will unlock the Partygoerachievement.

4. Try to climb the stairs in the room, but they'll fall to bits, souse portals to reach the upper floor. The door here is slightly ajar;"use" the door to open it. Climb the stairs in the chamber beyond andyou'll come up to a locked door in a link-fence wall. Um, let's justsuffice it to say that there is a portal-able wall in the space beyondthe fence, and you can shoot through the fence.

"Hello. Where are you? I know you're there. I can feel you here.Hello."

5. In the next chamber, use portals to safely pass through the left-hand fan (the fan blades block your portal shots but you can time ashot through them), then again use a portal to move to the far side ofthe large chamber that's visible from beyond the fan.

6. Face the way you came and shoot the blue portal high on theopposite wall of the chamber. Shoot the yellow portal onto a safewall and you should be able to jump/fall through and land on the

8/4/2019 Portal FAQ

18/25

gurney on the other side of the room.

7. Go in the door, just for fun, and look around at the offices andthings there. This is where you'll first see the name of the computerrunning the tests (GLaDOS: Generic Lifeform and Disk OperatingSystems) and that it was designed as a competitor to Black Mesa.You'll be able to enter several of the observation offices that you've

seen near the tests so far.. except that now you'll see they're..empty. And filled with rubble and discord.

[Note: The "Disk Operating System" is a very old computer joke. Thetext-only predecessor to Windows, which was used on PCs in the 80's,was called "MSDOS" (MicroSoft Disc Operating System), but there were anumber of other competing systems which all had "DOS" in their names(DRDOS, PCDOS, ProDOS, etc.) so GLaDOS is just continuing the trend.:) ]

8. Once you've finished enjoying the plot, move over to the other endof the gurney. Notice the marks on the wall telling you to go up, so

shoot the blue portal on the wall behind the partly collapsed platformat the top left of the chamber as you enter, then shoot a yellowplatform on the safe floor and step through. From there, you'll seeanother platform above the area where you came in. Shoot a blueportal onto the portal-able wall opposite that platform, and then usethe yellow portal still on the floor to fling yourself through theblue portal.

"What are you doing? You haven't escaped, you know. You're not evengoing the right way. Hello? Is anyone there?"

9. Climb the stairs in this area, and then jump into the broken cubetransport tube. After a short journey, you'll fall into a equipment

dispensor tube, where your weight breaks it and drops you back intothe area for the "impossible" test 9.

"Okay. The testing is over now. You win. Go back to the RecoveryAnnex for your cake. It was a fun test, and we're all impressed athow you won. The test is over. Come back."

10. Stand on the button to open the exit gate, and shoot the blueportal through it. Shoot the yellow portal onto any safe wall andpass through, then walk to the end and fall down the open lift shaft.

"Uh-oh. Somebody cut the cake. I told them to wait for you but theycut it anyway. There is still some left, so if you hurry back.."

11. Shoot the blue portal onto the ceiling above the storage boxesand the yellow one on the bottom of the lift shaft, and pass through,crouching. Climb onto the rising/falling pistons and, when the higherone is in the raised position, shoot the yellow portal onto the top ofthe platform that's back the way you came. Fall off the piston andfollow the chamber around to get to the storage boxes from the otherside. Crouch again, get under your previous portal, and then uncrouchunder it to stick your head through the portals! Jump out, then runalong the top of the crushing piston to the painted sign on the wall.

12. Shoot the blue portal through the gauze at the end of the

passage, then come back the way you came, walk across the top of thepiston again to get back to the top of the platform above the storageboxes, and shoot the yellow platform onto the floor and pass through

8/4/2019 Portal FAQ

it. Use a very small "fling" to get yourself to the ongoing passage -shoot the blue portal onto the wall behind and above you, the yellowportal onto the wall in front of you, then jump through.

(Map break)

"You're not even going the right way. Where do you think you're

going? Because I don't think you're going where you think you'regoing. Hello?"

13. Take the right branching corridor and climb the stairs. (There'sa secret area you can reach by going underneath the staircase andthen using portals to pass through a chainlink fence, then crouchingthrough a passage, but there isn't really anything interesting there.)While overviewing the piston room, shoot a portal right across theroom onto the upper of the two floors visible across the room, thenshoot the opposite portal onto any safe wall and pass through. Fromhere, if you move to the correct angle you can juuuuuuuust see aportalable wall at the back of the highest passage out of the room

(on your left as you face the pistons). It's there! Trust me onthis! Shoot a portal there, and then pass through to it. Pass alongthe corridor.

"Didn't we have some fun, though? Remember when the platform wassliding into the fire pit, and I said 'Goodbye', and you were like,'No Way', and then I was like, 'We pretended we were going to murderyou'. That was great. Is anyone there?"

14. Shoot the blue portal onto the ceiling of the area above you,then the yellow portal onto the ceiling above one of the pistons.Then stand on the piston and let it push you through the portal. Jumpacross the two horizontal pistons onto the platform. Use the platform

you are on, and the portal-able wall far above you, to perform a flingto access the area opposite that portal-able wall. You know how to doa fling by now, right?

15. Don't try and go through the fast moving pistons. Shoot a portalbehind them, then the opposite portal onto any safe wall and passthrough it.

"You really shouldn't be here. This isn't safe for you. It is nottoo late for you to turn back. I am not angry. Just go back to thetesting area."

16. Again, don't bother with the two moving pistons. Look carefullythrough the chamber they're in and you should be able to shoot aportal through onto the wall behind them, then walk through yourexisting portal to get there.

17. More pistons to not bother with. Shoot the blue portal above thepiston that the "over here" arrow points to and the yellow portal ontoany safe wall. Pass through. Then, shoot the blue portal onto thewall at the very top of the chamber, between the two pistons. Passback through the yellow portal, and carefully position yourself to be"inside the wall". You should be able to see the portal-able floor ofthe top of the chamber and shoot the yellow portal there. (If youcan't fire, just move forward a tiny bit more.) Then shoot the blue

portal onto any safe wall and pass through.

18. Walk through the chamber and fall down on the right hand side of

8/4/2019 Portal FAQ

20/25

the T junction in the cube delivery pipe. Crouch and walk along thepipe, then fall down onto the lower pipe that crosses it.

"You should have turned left before. It's funny, actually, when youthink about it. Someday we'll remember this and laugh, and laugh, andlaugh. Oh boy. Well, you may as well come on back."

19. Follow around the corner. When you reach the piston, turn to theleft and shoot the blue portal above the point where the piston hits.Walk back along the pipe and shoot the yellow portal onto a wall, thenwait for the piston to be fully extended, and carefully jump acrossthe killer floor through the portal. (You can make this jump but it'stricky - make sure to get as close as you can to the edge of the pipeyou're on.) Walk along the piston and onto the upper platform.Follow the platform along and then jump down the hole.

(Map Break)

20. Check out the "secret" storage area through the crouch tunnel,

then walk across into the next section. The pipes under you will openand drop you into a trap - don't worry, this is meant to happen.Three doors around the trap will open, each one revealing a turretbehind. As each door opens, quickly shoot the blue portal onto theside wall of the chamber inside, then the yellow portal onto any safewall, then pass through and push the turret over. Do this quickly toeach of the three turrets as it arrives.

21. I have no idea if this is how you're supposed to solve thispuzzle, but what the heck. Get one of the oil drums from the centralchamber, drop it in the chamber with the grabbing arm, then stand onit. You should now be able to see a portal-able wall in the room offto the right. Shoot a portal on it, then put the opposite portal on

any wall and pass through.

"You're not a good person. You know that, right? Good people don'tget up here. Can you hear me?"

22. Portal through the chain-link fence and push the blinking turretover. It can be tricky to find a portal-able spot here; I wentthrough on top of the table with the radio! :) Move the turret untilits blinking beam isn't shining at the opposite corner of the area anymore, then move over there and look up and towards the way you came infor a portal-able ceiling on the upper level above the cube transporttube. Portal through and walk around the walkway through the door.Crouch through the passageway, fall into the area with the turret andpush it over.

23. Enter the new area. There is another secret storage area on thefar wall of this area on the right. And how to get out? Well, thatnifty moving wall that let you in is portal-able on both sides, and itstopped at a 45 degree angle. You guessed it - it's flingin' time!Fling yourself onto the collapsed walkway and walk around thecorridor.

"This is your fault. It didn't have to be like this. I'm not kiddingnow. Turn back or I will kill you. I'm going to kill you, and allthe cake is gone. You don't even care, do you? This is your last

chance."

24. You can enter an office on the right here, but only for fun. Move

21/25

on, through the force field, and open the door. There's a nasty robothere that shoots rockets. Fortunately, it's really slow and easy tododge (but unfortunately one rocket kills you, so be careful). Youcan have fun making it shoot itself if you want, but all you need todo is make it shoot once (to break the glass on the room you're in),then run across to the otherside of the chamber it's in, make it shootat you again and dodge (to break the glass on the next room) then

jump through the glass and run out the door. While you're here,though, shoot a yellow portal onto one of the walls in its chamber.

25. Walk down the corridor and through the hall, then through thedoor. Hum, we need to break through another pane of glass. Hey, Iknow what to do! Shoot the blue portal on the wall opposite theglass. Hello again, Mr Rocket Turret! Would you be so kind as toshoot me again, so that I can dodge and your rocket will hit thisglass? Much obliged! Once that's done, shoot the blue portalsomewhere harmless (on the other side of the door you just camethrough is a good bet) and follow the arrow.

26. Oops, a crouch tunnel that's too high to get in. Again, I haveno idea if there's some better way of doing this with portals, butI just went and got a chair from the office with the rocket turret itand stood on it. Shoot a portal through the fan at the end onto thewall, then crawl back through the tunnel and shoot the oppositeportal onto safe wall and pass through.

27. Shoot a portal onto the wall above the red metal platform againstthe wall over the killer floor, then shoot the opposite portal ontoany safe wall and pass through, and walk along the red platform.

(Map break)

28. Walk along the red platform until you can see the safe floor atthe end of the passage. Shoot a portal onto it, then the oppositeportal onto the wall your platform is up against, and pass through.

29. Shoot a portal through the tiny little grating at the end of thisplatform, then shoot the opposite portal onto any safe wall and passthrough.

30. Walk around on the mucky floor (it makes you skid, but there'sno puzzle or anything with it! Weird) until you can see a portal-ablewall above you, and portal onto it. Be ready for a shock!

31. Well, I warned you! Huge numbers of turrets appear. Don'tpanic. Treat this exactly like you did the earlier trap. Portal ontothe side wall of one of the turret chambers and push the turret over.Then, from inside the chamber, try to find the wall of another turretchamber, portal to it, and push over that turret too.. and keep goingand climbing that way.

32. Once you've got all the turrets.. well, you saw that two of thoseturrets had 45 degree walls protecting them? Could it be flingin'time? Yes, you've got it. You need to fling from the higher of thetwo walls, but you may need to fling from (or, if you're careful, juststand on) the lower 45 degree wall in order to see it. Use the yellowportal on the 45 degree wall and the blue portal on the floor. This

is a difficult fling and it may take you a lot of attempts, but it ispossible.

8/4/2019 Portal FAQ

22/25

33. As you move down the next corridor, you face two turrets. Hey, Iwonder if the turrets would like to try doing a fling? Hide behindthe pipes to avoid their fire, and shoot blue portals under them.

34. Leave a blue portal underneath the upward shaft that you're atthe bottom of. Move back to the platform and shoot the yellowplatform on the floor of the huge chamber you just came from, and then

jump down into it to be sent flying up the shaft. Where you land, youshould be able to see a portal-able wall above and in front of you;shoot the yellow portal there, then gently drop through the blueportal again. (Don't fall through the shaft into the blue portal.)

35. Cross over the big scary bridge and into the offices beyond.Explore the office a little if you like, then climb the stairs andcross the big bridge into the silo, and, hey, it's..

GLADOS ---------------------------------------------------------------"Well, you found me. Congratulations. Was it worth it? Becausedespite your violent behaviour, the only thing you've managed to break

If that thing is important,why don't I know about it? I'll tell you what that thing isn't. Itisn't yours. So leave it alone. Are you even listening to me?"

1. No, you don't really have to wait for that whole spiel. That'swhat Glados says if you don't do anything. I'm sure you know it's atrick - but ya gotta do it. Look at the back of the room wherethere's an incinerator and place a portal near it. Climb the stairson the left of the room, and enter the armored chamber, placing theopposite portal on the nearest portal-able wall outside first. Pressthe button in the chamber to open the furnace, then pick up the'thing' Glados dropped and throw it in the furnace. (Without theportals you can't get to the incinerator fast enough.)

"You're kidding me. Did you just stuff that Aperture Science Thing WeDon't Know What It Does into an Aperture Science EmergencyIntelligence Incinerator!? That has got to be the dumbest thing th-whoa.. whoa.. whoa.... Good news.. I figured out what that thing you

just incinerated did. It was a morality core they installed after Iflooded the Enrichment centre with a deadly neurotoxin, to make meSTOP flooding the Enrichment Centre with a deadly neurotoxin. So get

comfortable while I warm up the neurotoxin emitters.. Oh. That coremay have had some ancillary responsibilities. I can't shut off theturret defenses. Oh well. If you take my advice you should just liedown in front of a rocket. It'll be a lot less painful than theneurotoxin... Alright, just keep doing whatever you think you'redoing. Killing you and giving you good advice aren't mutuallyexclusive."

2. Ok, time to kill Glados! You have to hit her three times and eachhit is a two-step process.a) Put the yellow portal under Glados and the blue portal on a wall.

Get the rocket turret to shoot at you, and redirect the rocketthrough the portal to hit Glados. It doesn't matter where you hither, as long as you do hit her. The easiest way to do this is tostand with your back to the turret, look through it at Glados,look at the turret's search beam (which can usually pass throughyou, for some reason) and move carefully until the beam is linedup, then stop, wait until you hear the turret beep, and get theheck out of the way before you get a rocket up the bottom.

b) Pick up the bit of Glados that falls off. This is harder than itsounds, because Glados has a weird picky-uppy ray that she uses tomove the items to awkward locations. See below for how to get tothe locations.

c) Repeat step 1) from this room to stick the core in theincinerator.

Oh, yea, there's that nasty neurotoxin business. Basically, if youdon't hit Glados three times within about six minutes you're dead.In an unusually helpful mood, Glados provides a countdown for you.

So, here's how to get the three Cores:

Curiosity Core:On top of some pipes. Just put a portal on the wall behind them andreach through.(Core)"Who are you? What's that? That thing has numbers on it. Is that agun? I smell something burning.."(Glados, when core is destroyed)"You think you're doing some damage? 2 plus 2 is... *fizzfizzfizz*10. ... ... ... In base 4. I'm fine. By the way, I only let youlive this long because I was curious about how you would behave.Unfortunately, I can't get the neurotoxin into your head any faster."

Knowledge Core:On top of one of the "fins" at the top of Glados. Put a portal on thewall high above Glados on that side and jump through - it's a trickyjump, but possible.(Core)"Two cups rhubarb (sliced), two-slash-three cup granulated rhubarb,one tablespoon all-purpose rhubarb.."(Glados, when core is destroyed)"Neurotoxin.. so deadly.. choking.. Hahahaha. When I said deadly ithad major sarcasm quotes around it. I could take a bath in thisstuff. Honestly, it's not deadly at all - to me. You, on the other

hand, will find its deadliness rather less funny."

Floating in mid-air. This is similar to the previous one, although itdoesn't look it - you have to put a portal high on a nearby wall, thenjump down so you land ON TOP of it.(Core)"GRRRRRR! GRRRRRR! GRRRRRRR! GRRRRR!"(Glados, when core is destroyed - end of game)"I'm not sure what's going on outside.. all I know is, I'm the only

thing standing between us and the world.. And I... O-o-o-o-o-o-o-o..*BOOM*"

You are thrown up into the air, and appear in the outside world asbits of Glados's installation rain down around you.

Then.. deep in the bowels of a complex.. is a cake. Surrounding it,several lighted spheres, looking eerily like Glados' modules, start toactivate. A robot arm comes down and snuffs out the cake candle.

Hey! You've finished Portal! Enjoy the ending song, and then whenyou're back at the menu, wait a few moments for the camera view to

pan... Oh, you get the Heartbreaker achievement too.

A few more choice Glados quotes from the final battle:

"That thing you just broke isn't important to me. It's the FluidCatalytic Cracking Unit. It makes shoes for orphans. Nice jobbreaking it, hero."

"I'd just like to point out that you were given every opportunity tosucceed. There was even going to be a party for you. A great bigparty. All of your friends were invited too. I invited your bestfriend the Companion Cube, but of course he couldn't come because youmurdered him. None of your other friends could come because you don't

have any other friends because you are unlikable. It says so here inyour file, 'unlikable', liked by no one, all formal and everything.It also says you're adopted."

"Speaking of curiousity, I expect you're curious about what happensafter you die. Guess what? I know. But you'll find out first-handbefore I finish explaining it to you. But, in summary, I'd live asmuch as you can in the next few minutes."

AND... THAT SONG -----------------------------------------------------

"Final Test Report (Still Alive)"By "Geek Troubador" Jonathan Coulton

This was a triumph.I'm making a note here: Huge Success.It's hard to overstate my satisfaction.

Aperture Science,We do what we must, because we can.For the good of all of us(except the ones who are dead.)

But there's no sense crying over every mistake.You just keep on trying till you run out of cake.

And the science gets done, and you make a neat gunFor the people who are still alive.

[Personnel File Addendum:Dear ,]

I'm not even angry.I'm being so sincere right now.Even though you broke my heart and killed me;

And tore me to pieces;And threw every piece into a fire.As they burned, it hurt becauseI was so happy for you.

Now these points of data make a beautiful line,And we're out of beta, we're releasing on time.So I'm GLaD. I got burned. Think of all the things we learnedFor the people who are still alive.

[Personnel File Addendum Addendum:One Last Thing:]

Go ahead and leave me.I think I prefer to stay inside.Maybe you'll find someone else to help you.

Maybe Black Mesa.That was a joke. Ha ha, fat chance.Anyway, this cake is great;It's so delicious and moist.

Look at me still talking, when there's science to do.When I look out there, it makes me glad I'm not you.I've experiments to run, there is research to be done

On the people who are still alive.[PS:] And believe me, I am still alive.[PPS:] I'm doing science and I'm still alive.[PPPS:] I feel fantastic and I'm still alive.[FINAL THOUGHT:] While you're dying I'll be still alive.[FINAL THOUGHT PS:] And when you're dead I will be still alive.Still alive, still alive, still alive.
