This is the fifth Bonus map of the game. It is unlocked when the original [[Portal Test Chamber 17|Test Chamber 17]] has been completed.

== Hazards ==
* [[High Energy Pellet]]s
* [[Weighted Storage Cube|Cube Hazard]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* Use two portals to get into the rat hole behind the projecting panel and bring out all the security cameras.
* Stack the cameras up in the recess where you're supposed to jump across from the last lift platform. Put the [[Weighted Companion Cube]] on top and scramble up.
* Turn back at the edge and crouch down to pick up the Weighted Companion Cube, then you can be on your merry way.

=== Steps ===
* This chamber has long stretches of portal-unfriendly surfaces, so there aren't many opportunities to use portal trickery to keep your step-count down. The key technique for most of the way is the "bunny hop" which lets you cover long distances in a minimum of steps. There are tutorials online, but in essence you need to move forwards and jump, then crouch ''just before you would land'' to maximize the jump length. With good timing, and especially with forward momentum over longer courses, you can make considerable savings in steps.
* Check your step count at each of these points. If you are over the suggested count you probably aren't going to hit the target of 150 steps, so start again:
** Under the cube chute: 16
** At the first pellet wall, ready to go around the corner and run down the corridor: 32
** In the chamber with the two emitters, at the bottom of the steps to the second corridor: 50
** On the catwalk above the main chamber, with a view of the projecting panel: 84
* Place your red portal on the first pellet wall as soon as you reach it. All the pellets you need will come from there, but it has to be the first wall: the second emitter shuts off as soon as either pellet is captured.
* When you reach the catwalk, drop the cube and move out so you can see the face of the projecting panel below (your step count should hopefully be not much more than 80). You don't need a great view of the face: the idea is just that you can place the blue portal on the wall directly facing you and make the pellets deflect off the edge. With experimentation, it's possible to bounce pellets into both of the other chambers by doing this: use very small changes of the portal position to fine-tune it. The third receptacle is easily hit by setting a portal on the sloping face.
* Once the three lifts are up, use portals to set the cube on friendly floor where you'll be able to see it from the lift platforms: for instance, against the wall to the right of the doorway that leads into the small side-room. Then portal yourself down. You want to be right of the doorway, but as close as you can get to the end of the portal-friendly tiles. You'll be placing a portal beside the observation window above this doorway, and you need to be aligned with that.
* Turn back to face the wall and set your red portal beside the window, as high as possible. Shoot the blue portal at your feet, then aim your fall so you go through the floor portal again and shoot out over the lifts. Crouch as you approach the middle platform, and do a quick back-step to brake before you fall off.
* From the platform, turn around and shoot the red portal beside the cube. You want a corner of the cube hanging into the portal so you can grab it from the other side.
* Carry on to the button room, using the bunny-hop where appropriate (but not for getting upstairs). Stop as soon as you're on the friendly floor. Put the blue portal on the floor beside you, crouch and reach through to get the cube.
* Portal across to the far side of the button. It's a short distance, but getting around obstructions can take a lot of steps. Bunny-hop down to the switch room and finish the level.
==== Alternative strategy for the lifts ====
It's possible to raise only two of the lifts and then do a curved jump from the second platform to the escape corridor. The technique involves simultaneously moving forwards, strafing right and turning right. If executed correctly it will enable you to do a beautiful, hooking turn in mid-air, in open defiance of Newton's Laws.
==== Alternative strategy using the "portal bump" glitch ====
* Follow the steps above until you reach the catwalk above the main chamber. However you can do this route and get under 130 steps, so the numbers above aren't really that relevant.
* [https://wiki.sourceruns.org/wiki/Portal_Bumping Portal bump] to the room with the button. Stand right against the glass on your left, shoot your blue portal onto the floor close beside it, then scan your sights around the left edge of the portal until the red portal indicator lights up. You can then fire the red portal and it will appear on the other side of the glass.
* Place the cube in the room with the portal and jump through.
* Place the cube on the button and bunny hop to the Pedestal Button and press it.
* Bunny hop to the cube and bunny hop to the incinerator.
* Bunny hop (or [https://wiki.sourceruns.org/wiki/Accelerated_Back_Hopping ABH]) to the chamberlock.

=== Time ===
* Grab the cube, get up the steps and run along the two pellet corridors PDQ.
* When you reach the catwalk above the main chamber, go to the end and use a twisting motion to fling the cube as far as you can down the side passage where the lifts are.
* As you turn back, shoot a portal at the camera above the doorway across from the side passage. Turn back to the camera above the stairs where you just came out, and shoot the other portal at it. Grab that camera, take it to the end of the catwalk and throw it down after the cube.
* As you jump down into the side passage, shoot a portal at the wall opposite. Shoot the other portal at the camera from above the doorway, which should now be lying on the portal-friendly floor. Grab the camera and carry it down to the end of the passage.
* Stack the two cameras beside the exit ledge, put the cube on top and scramble up. Turn and crouch to retrieve your cube, and get going.

This is the sixth Bonus map of the game. It is unlocked when the original [[Portal Test Chamber 18|Test Chamber 18]] has been completed.

== Hazards ==
* [[High Energy Pellet]]s
* [[Weighted Storage Cube|Cube Hazard]]
* [[Goo]]
* [[Turrets]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* Go out to the end of the walkway and over against the wall on your left. Crouch and look at the ceiling opposite. To the right of it, you should be able to see a bit of the adjacent higher ceiling. Shoot a portal there.
* Shoot the second portal onto the walkway where you can move around it and look through. Get into a position where you are facing towards the 4-dot platform with minimal obstructions. There are some blocks sticking out of the side wall that can queer your shot here, so watch out for those.
* This is the tricky part. Crouch and step into the portal. As you fall, shoot a portal across to the 4-dot floor, aiming for the left side of it. At the same time, you have to be directing your fall so you land on the 3-dot platform. Quickly shoot the second portal under your feet before you touch down. If you can get all this coordinated you will come flying up from the 4-dot platform and you can shift yourself to land right by the big button. High five if you want.
* Shoot the red portal onto the floor way down below.
* Go in and press the small button. Take cover behind the moving panel as it slides out, then as soon as it locks in place dash out to place your blue portal on it, then run back again to the big button and jump off the platform and through the red portal to propel yourself across the turret room to the cube.
* Hide behind the cube until the turrets calm down, then pick up the cube and walk off the edge. Start moving backwards right away and with a bit of luck you'll land in the lower niche. Put the blue portal on one of the side walls and go through it with the cube to emerge on the platform down below the big button.
* Shoot the blue portal up to the projecting panel above the exit door. Pick up the cube again, step through and jump off the platform and back through the blue portal to fling yourself and the cube over to the button. Put the cube on the button.
* Jump down to the lower floor and step through the portal again, then exit via the now open door and do the leap-frogging ascent in the approved manner. A mere 14 portals if you got it all right.

=== Steps ===
* Run-jump out to the edge of the first walkway, finishing close to the left side.
* Crouch and look at the ceiling opposite. To the right of it, you should be able to see a bit of the adjacent higher ceiling. Shoot a portal there and the other at your feet. As you fall, move towards the higher platform.
* Place a portal on the next ceiling, near the back left corner. Place the other on the ground near you, where you can see into it. Peer in and orientate yourself so you will be facing the pushed-out wall panel above the exit, then jump in. As you fall, shoot a portal onto the pushed-out panel and the other onto the floor below you. You will be propelled over the floor button, hopefully landing fair in the middle of the doorway with nothing obstructing you.
* Hop over to the small button, positioning yourself on the far side of it, near the hydraulic door. Step count here should be about 20.
* Activate the button and hop onto the framing on the inside of the door, saving a few steps by letting the ram carry you out. You'll fall off when the door stops and tilts up. Nip out and shoot a portal onto the face of the sloping panel, then jump over the edge to the low floor, shooting your other portal as you fall, to go flying across the chamber.
* As you approach the cubicle, do a physics-defying mid-air turn (by simultaneously moving forwards and right, and turning to your right) to curl in behind the cube. Squat there and start picking off turrets by portalling the [[High Energy Pellet|High-Energy Pellets]] onto them. This may take a while as you won't be able to see where the turrets' sighting beams strike the walls, and you may have to hop forwards with your cube before taking out the last couple. If you're impatient you can take your chances with leaving the turrets live, but remember that taking a hit usually costs you a step.
* When you're ready, step off the ledge with your cube and manoeuvre back into the lower niche. About 40 steps now.
* Toss the cube over to one of the side walls and put a portal behind it, then shoot the other portal across the water so it's directly above the centre of the moving panel.
* Hit the button then hop back, grab your cube and go through the portal. You should land on the hydraulic ram, where you can squat down and wait for it to carry you in.
* Make your way out to the floor button and set your cube on it. Then shoot a portal to the wall beside the exit door facing you. Jump down to the lower platform, set a portal on the floor and go through. Crouch down and aim through the doorway to place a portal on the ceiling at the end of the corridor, then shoot the other portal under you to drop through.
* Set a portal on the first platform then hop off into the pit and begin your ascent in the normal way.
* As you fly out of the inclined panel at the end, try another aerial turn to swoop into the final exit, saving a few more steps.

=== Time ===
* Follow the same route as for least steps to reach the small button - but GO FASTER.
* As the panel is pushing out, slip under the ram and out on the left side where the turrets can't get you. Place the blue portal on the wall above the low-level floor.
* As soon as the door is fully open, shoot the red portal onto it and jump through. While you're falling, shoot the blue portal to the floor under you.
* Coming in to land, do an aerial turn (see above) to curl in behind the cube. Grab the cube, step off the ledge and edge back into the lower niche as you fall.
* Toss the cube over to one of the side walls and put a portal behind it, then shoot the other portal across the water so it's above the left side of the moving panel.
* Hit the button then hop back, grab your cube and go through the portal, landing on the floor behind the panel.
* The rest of the route is just like least steps, but again - GO FASTER.
* Don't forget that aerial turn at the end.

This is the fifth Bonus map of the game. It is unlocked when the original [[Portal Test Chamber 17|Test Chamber 17]] has been completed.

== Hazards ==
* [[High Energy Pellet]]s
* [[Weighted Storage Cube|Cube Hazard]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* Use two portals to get into the rat hole behind the projecting panel and bring out all the security cameras.
* Stack the cameras up in the recess where you're supposed to jump across from the last lift platform. Put the [[Weighted Companion Cube]] on top and scramble up.
* Turn back at the edge and crouch down to pick up the Weighted Companion Cube, then you can be on your merry way.

=== Steps ===
* This chamber has long stretches of portal-unfriendly surfaces, so there aren't many opportunities to use portal trickery to keep your step-count down. The key technique for most of the way is the "bunny hop" which lets you cover long distances in a minimum of steps. There are tutorials online, but in essence you need to move forwards and jump, then crouch ''just before you would land'' to maximize the jump length. With good timing, and especially with forward momentum over longer courses, you can make considerable savings in steps.
* Check your step count at each of these points. If you are over the suggested count you probably aren't going to hit the target of 150 steps, so start again:
** Under the cube chute: 16
** At the first pellet wall, ready to go around the corner and run down the corridor: 32
** In the chamber with the two emitters, at the bottom of the steps to the second corridor: 50
** On the catwalk above the main chamber, with a view of the projecting panel: 84
* Place your red portal on the first pellet wall as soon as you reach it. All the pellets you need will come from there, but it has to be the first wall: the second emitter shuts off as soon as either pellet is captured.
* When you reach the catwalk, drop the cube and move out so you can see the face of the projecting panel below (your step count should hopefully be not much more than 80). You don't need a great view of the face: the idea is just that you can place the blue portal on the wall directly facing you and make the pellets deflect off the edge. With experimentation, it's possible to bounce pellets into both of the other chambers by doing this: use very small changes of the portal position to fine-tune it. The third receptacle is easily hit by setting a portal on the sloping face.
* Once the three lifts are up, use portals to set the cube on friendly floor where you'll be able to see it from the lift platforms: for instance, against the wall to the right of the doorway that leads into the small side-room. Then portal yourself down. You want to be right of the doorway, but as close as you can get to the end of the portal-friendly tiles. You'll be placing a portal beside the observation window above this doorway, and you need to be aligned with that.
* Turn back to face the wall and set your red portal beside the window, as high as possible. Shoot the blue portal at your feet, then aim your fall so you go through the floor portal again and shoot out over the lifts. Crouch as you approach the middle platform, and do a quick back-step to brake before you fall off.
* From the platform, turn around and shoot the red portal beside the cube. You want a corner of the cube hanging into the portal so you can grab it from the other side.
* Carry on to the button room, using the bunny-hop where appropriate (but not for getting upstairs). Stop as soon as you're on the friendly floor. Put the blue portal on the floor beside you, crouch and reach through to get the cube.
* Portal across to the far side of the button. It's a short distance, but getting around obstructions can take a lot of steps. Bunny-hop down to the switch room and finish the level.
* '''Alternative strategy for the lifts''' It's possible to raise only two of the lifts and then do a curved jump from the second platform to the escape corridor. The technique involves simultaneously moving forwards, strafing right and turning right. If executed correctly it will enable you to do a beautiful, hooking turn in mid-air, in open defiance of Newton's Laws.

=== Time ===
* Grab the cube, get up the steps and run along the two pellet corridors PDQ.
* When you reach the catwalk above the main chamber, go to the end and use a twisting motion to fling the cube as far as you can down the side passage where the lifts are.
* As you turn back, shoot a portal at the camera above the doorway across from the side passage. Turn back to the camera above the stairs where you just came out, and shoot the other portal at it. Grab that camera, take it to the end of the catwalk and throw it down after the cube.
* As you jump down into the side passage, shoot a portal at the wall opposite. Shoot the other portal at the camera from above the doorway, which should now be lying on the portal-friendly floor. Grab the camera and carry it down to the end of the passage.
* Stack the two cameras beside the exit ledge, put the cube on top and scramble up. Turn and crouch to retrieve your cube, and get going.

This is the first Bonus map of the game. It is unlocked when the original Test Chamber 13 has been completed.

== Hazards ==
* [[High Energy Pellet]]s
* [[Weighted Storage Cube|Cube Hazard]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* Shoot a portal onto the wall behind the [[Weighted Storage Cube]] and another on the wall beside the button. Reach in to pick up the cube and place it on the button, then step through the portal and walk over to the open door.
* Place a portal on the wall next to the [[Heavy Duty Super-Colliding Super Button]] in the next room.
* Make a save before attempting to throw the Cube onto the other button.
* The portal on the wall beside where you are standing is your exit. Shoot the other one through the open door, then jump through.

=== Steps ===
* When using floor portals, cancel your exit portal as soon as you pop out of it, by firing the same colour somewhere else. This is easy if you have a portal-friendly ceiling above, but can be tricky if you have to cast around for a surface mid-flight.
* Place a portal right beside the button and another right in front of the chamberlock. Jump through and cancel the exit portal. With luck, you can do this in two steps.
* Throw a portal onto the wall behind the cube and the other onto the floor in front of you. Crouch down to pick up the cube without taking any steps. Don't reach through a wall or you will have to step back to get the cube clear of the sides.
* Set the cube on the button then fire a portal through the walkway and the open door onto the ceiling above the higher button. Don't waste any steps while doing this.
* Put your other portal on the floor in front of you then pick up the cube and drop it through. You're trying to get it on a corner of the platform, not on the button itself.
* Fire this same portal right under your feet so you drop through onto the button. If you're on top of the cube, start all over again - from your last quicksave, that is ;-)
* Portal the cube onto the other button. If you can't see it, revert to an earlier save.
* Place a portal on the floor or the nearby wall, and another on the floor near the exit.
* Use floor-to-floor to get as close as possible to the [[Chamberlock]].

=== Time ===
* Grab the Cube though the portal, don't waste time traveling into the portal to place it on the button.

}}

This is the third Bonus map of the game. It is unlocked when the original Test Chamber 15 has been completed.

== Hazards ==
* [[High Energy Pellet]]s
* [[Goo]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* It's possible to get the first energy pellet into the receptacle with just two portals, but it takes a bit of experimentation (using quick-save/reload). The sweet spot for the exit portal is a bit to the left of where the lift is. Let the pellet bounce around until it hits the receptacle.
* Don't bother with the second energy pellet puzzle. Get past the slime channel by shooting portals through portals:
** Go to the start of the channel and shoot one portal down to the far end and the other on the wall beside you.
** Creep through the portal just until you can shoot again without dropping through. There's a telltale buzzing noise and the launcher sight changes.
** Shoot your ''exit'' portal down to the far end. Go for the wall that faces around the corner, not the one facing back to you. As soon as you shoot, step back: if you don't get out of the portal before your shot lands, you'll drop into the slime.
** Edge through again and shoot a portal into the far chamber.
* In the final room, put a portal at the foot of the victory lift, then step up onto one of the other platforms, put your second portal on the floor below and jump through. Manoeuvre onto the victory lift platform as you fly up through the exit portal.

=== Steps ===
* When using floor portals, close your exit portal as soon as you pop out of it, by firing the same colour somewhere else. This is easy if you have a portal-friendly ceiling above, but can be tricky if you have to cast around for a surface mid-flight.
* Use floor-to-floor whenever possible - you can cover any distance without taking a single step. Place your exit portal first, then shoot the entry portal at your feet and throw the exit portal away as you come through.
* Place a portal as far ahead as you can see and another right in front of the chamberlock. Jump through and cancel the exit portal.
* Use floor-to-floor to get right against the emancipation grid.
* Continue as for least portals.

=== Time ===
* Negotiating this map quickly entails some fancy portal tricks. The key is to get your portals out quickly and accurately.
* Portal from just outide the chamberlock into the first wall-jumping chamber. Turn and place your portal on the projecting slab and get the jump going right away.
* As soon as you can see into the first pellet room, shoot your two portals onto the walls. Accuracy is all-important here - get the exit portal centred correctly above the doorway to the lift. But work fast to get the portals in place so you don't have to wait for a second pellet.
* Run-jump to the emancipation grid and wait for the pellet to come out of your exit portal. As soon as it emerges, cross the grid and place your two portals. If your initial exit portal over the lift was accurately set, you won't have to let the pellet bounce and mark the wall for you before positioning your portal. Wait again for the pellet to emerge from the exit portal, then run out immediately.
* Don't wait for the lift: as soon as you see a gap, shoot a portal onto the wall above and the other at your feet to get you up there.
* The next room has a wide area of dead floor in front of the entrance. If you portal into it you'll end up having to run back to get into the side room with the steps. It's quicker just to run-jump into the room, shoot your first portal back onto the projecting slab and dash into the side room to start your jump.
* Use portal-through-portal (see above) to get over the slime. Try to get your last portal near the centre of the final room, where the ceiling is portal-friendly. Avoid the bouncing pellet, though - they have been shown to have a detrimental effect on human health.
* Turn to face the victory lift, then place a portal on the ceiling directly above you and the other under your feet. As you fall, shoot the ''ceiling'' portal onto the floor right in front of the victory lift. Manoeuvre onto the lift as you pop up, and dash for the chamberlock.

This is the fourth Bonus map of the game. It is unlocked when the original [[Portal Test Chamber 16|Test Chamber 16]] has been completed.

== Hazards ==
* [[Weighted Storage Cube|Cube Hazard]]
* [[Turrets]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* Don't use any portals to take out the turrets. Close in on them using the cubes as shields.
* At the last turret, lean round the edge of the open door and shoot a portal through the two fences onto the tiny visible patch of portal-friendly wall.
* Alternatively you can gather up all the cubes and use them to build steps to get you over the barrier. Jump over with a cube to disable the turret, then use your two portals to get through the final fence.

=== Steps ===
* Use floor-to-floor portals wherever possible. Place your exit portal first, then shoot the other one at your feet and throw the exit away to somewhere else as you land. Moving like this costs no steps.
* From the Chamberlock, shoot a portal up to the door. Shoot the other in front of you and jump through, dumping the exit portal to the ceiling as you emerge.
* While GLaDOS is talking, set a portal on the ceiling or wall nearby (but not directly overhead). As soon as the spiel ends and the door opens, shoot the other portal under the turret. Then shoot the first one at your feet and you'll pop up where the turret used to be. You'll have to run-jump over the next section.
* When you see the next turret, aim a portal underneath it, then use floor-to-floor to get where it was.
* Aim your portal at the floor way up at the far end of the hall and floor-to-floor again. Ideally you want to be a bit in front of the two cubes, with a clear view of the corridor between the two turrets.
* Put a portal high up on any convenient wall and shoot the other under the boxes to drop them through onto the portal-friendly tiles. This makes them a bit easier to manipulate.
* Use your portals to place the cubes in between the two turrets, with a gap between them big enough for you to stand in. Fiddle with their positioning until they are breaking the turret detector beams.
* Portal yourself into the gap between the cubes and crouch. From here, take out each of the turrets in turn by dropping the cubes on them.
* Floor-to-floor up to the end of the friendly tiles where you can see into the side room with all the cubes in it. Floor-to-floor again to get into the room.
* Use your portals to move one or two boxes into the doorway, then portal yourself right behind them and crouch. Drop cubes onto the turrets.
* Drop some more cubes out onto the portal-friendly tiles where you'll be able to use them, then go out yourself. Put a cube in front of the next doorway and crouch behind it.
* Set a portal on the wall behind the turret in the far left corner and send a cube through to knock it over.
* Shoot a portal underneath the turret on the near right.
* If you have another cube on friendly ground, send it through to somewhere in sight of the last turret and position yourself behind it.
* Kill the third turret by firing a portal at the security camera behind it.
* Lift a cube and set it on the button. If you're in sight of the next turret, shoot a portal under it.
* Aim your portal through the two fences and go through.
* Stick a portal on the floor and chuck the last turret into it, then use portals to get right up to the Material Emancipation Grill before run-jumping to the Chamberlock.

=== Time ===
* You can't do anything in the first 20 seconds while GLaDOS is talking - except run up to the door and get your exit portal onto the ceiling ready for the turrets you're going to send through.
* As soon as the announcement is over, shoot a portal under the turret and get running.
* As you come in sight of the next turret, shoot a portal anywhere on the wall behind it and the other onto the wall in front of you. Keep running.
* Shoot your next portal up the hall and the other onto the floor and run on through. You want to be near the cubes.
* Grab a cube and run for the nearer of the two turrets (on the left) then run on down the hall for the other one, still holding your cube.
* Turn around and keep motoring on, knocking down the next two turrets with your cube. If the clock is much past 40 seconds by this point, you're probably not making the target of 52.
* Drop the cube as soon as you're on friendly floor and aim a portal at the wall behind the far turret in the next room. Portal your cube through to kill it.
* Dash in and grab the turret on the right. Try to make sure the last turret doesn't see you doing this because if it starts shooting you won't be fast enough for gold. Barge on around the corner and knock the third turret down, then throw the other one to the floor vewy woughly.
* Stand on the button and shoot your portal through the two fences, shoot the other onto the floor and go through.
* Ignore the last turret - just keep running.

* In the final room, put a portal at the foot of the victory lift, then step up onto one of the other platforms, put your second portal on the floor below and jump through. Manoeuvre onto the victory lift platform as you fly up through the exit portal.

=== Steps ===
* When using floor portals, close your exit portal as soon as you pop out of it, by firing the same colour somewhere else. This is easy if you have a portal-friendly ceiling above, but can be tricky if you have to cast around for a surface mid-flight.
* Use floor-to-floor whenever possible - you can cover any distance without taking a single step. Place your exit portal first, then shoot the entry portal at your feet and throw the exit portal away as you come through.
* Place a portal as far ahead as you can see and another right in front of the chamberlock. Jump through and cancel the exit portal.
* Use floor-to-floor to get right against the emancipation grid.
* Continue as for least portals.

=== Time ===
* Negotiating this map quickly entails some fancy portal tricks. The key is to get your portals out quickly and accurately.
* Portal from just outide the chamberlock into the first wall-jumping chamber. Turn and place your portal on the projecting slab and get the jump going right away.
* As soon as you can see into the first pellet room, shoot your two portals onto the walls. Accuracy is all-important here - get the exit portal centred correctly above the doorway to the lift. But work fast to get the portals in place so you don't have to wait for a second pellet.
* Run-jump to the emancipation grid and wait for the pellet to come out of your exit portal. As soon as it emerges, cross the grid and place your two portals. If your initial exit portal over the lift was accurately set, you won't have to let the pellet bounce and mark the wall for you before positioning your portal. Wait again for the pellet to emerge from the exit portal, then run out immediately.
* Don't wait for the lift: as soon as you see a gap, shoot a portal onto the wall above and the other at your feet to get you up there.
* The next room has a wide area of dead floor in front of the entrance. If you portal into it you'll end up having to run back to get into the side room with the steps. It's quicker just to run-jump into the room, shoot your first portal back onto the projecting slab and dash into the side room to start your jump.
* Use portal-through-portal (see above) to get over the slime. Try to get your last portal near the centre of the final room, where the ceiling is portal-friendly. Avoid the bouncing pellet, though - they have been shown to have a detrimental effect on human health.
* As you come out through the floor, shoot your ''entry'' portal onto the ceiling above. You should then drop back through the floor and come out through the ceiling. While falling, shoot the ''ceiling'' portal onto the floor right in front of the victory lift. Manouevre onto the lift as you pop up, and dash for the chamberlock.

=== Portals ===
* It's possible to get the first energy pellet into the receptacle with just two portals, but it takes a bit of experimentation (using quick-save/reload). The sweet spot for the exit portal is a bit to the left of where the lift is. Let the pellet bounce around until it hits the receptacle.
* Don't bother with the second energy pellet puzzle. Get past the slime channel by shooting portals through portals:
** Go to the start of the channel and shoot one portal down to the far end and the other on the wall beside you.
** Creep through the portal just until you can shoot again without dropping through. There's a telltale buzzing noise and the launcher sight changes.
** Shoot your ''exit'' portal down to the far end. Go for the wall that faces around the corner, not the one facing back to you. As soon as you shoot, step back: if you don't get out of the portal before your shot lands, you'll drop into the slime.
** Edge through again and shoot a portal into the far chamber.
* In the final room, put a portal at the foot of the victory lift, then step up onto one of the other platforms, put your second portal on the floor below and jump through. Manoeuvre onto the victory lift platform as you fly up through the exit portal.

This is the second Bonus map of the game. It is unlocked when the original Test Chamber 14 has been completed.

== Hazards ==
* [[Weighted Companion Cube|Cube Hazard]]
* [[High Energy Pellet]]s
* [[Goo]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* Place a floor portal beside the victory lift then run up the stairs to the pellet receptacle. Wait for the stairs to retract before placing your second portal in the floor of the pit and diving through.

=== Steps ===
* When using floor portals, cancel your exit portal as soon as you pop out of it, by firing the same colour somewhere else. This is easy if you have a portal-friendly ceiling above, but can be tricky if you have to cast around for a surface mid-flight.
* Place a portal close in front of the victory lift and another right in front of the chamberlock. Jump through and cancel the exit portal.
* Shoot a portal on the wall above the stair pit.
* Shoot the other portal at your feet and as you fall, shoot the exit portal (the one on the wall) onto your landing spot.
* As you come flying up in front of the lift, move backwards to land on the platform.
* Jump, don't walk, to the chamberlock.
=== Time ===
* Like least steps, only faster.
* Don't waste time portalling to the lift - just keep run-jumping.

This is the first Bonus map of the game. It is unlocked when the original Test Chamber 13 has been completed.

== Hazards ==
* [[High Energy Pellet]]s
* [[Weighted Storage Cube|Cube Hazard]]

== Strategy ==
{{Spoiler|block=yes|
=== Portals ===
* When retrieving the Weighted Storage Cube, try to use the same portal that you placed on the bottom.
* Place a portal on the wall next to the [[Heavy Duty Super-Colliding Super Button]] in the next room.
* Make a save before attempting to throw the Cube onto the other button.
* Walk though the same portal on the wall near the button when reaching the exit.

=== Steps ===
* When using floor portals, cancel your exit portal as soon as you pop out of it, by firing the same colour somewhere else. This is easy if you have a portal-friendly ceiling above, but can be tricky if you have to cast around for a surface mid-flight.
* Place a portal right beside the button and another right in front of the chamberlock. Jump through and cancel the exit portal. With luck, you can do this in two steps.
* Throw a portal onto the wall behind the cube and the other onto the floor in front of you. Crouch down to pick up the cube without taking any steps. Don't reach through a wall or you will have to step back to get the cube clear of the sides.
* Set the cube on the button then fire a portal through the walkway and the open door onto the ceiling above the higher button. Don't waste any steps while doing this.
* Put your other portal on the floor in front of you then pick up the cube and drop it through. You're trying to get it on the platform, not the button.
* Fire this same portal right under your feet so you drop through onto the button. If you're on top of the cube, start all over again - from your last quicksave, that is ;-)
* Portal the cube onto the other button. If you can't see it, revert to an earlier save.
* Place a portal on the floor or the nearby wall, and another on the floor near the exit.
* Use floor-to-floor to get as close as possible to the [[Chamberlock]].

=== Time ===
* Grab the Cube though the portal, don't waste time traveling into the portal to place it on the button.
