* 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.

* 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. (It is possible to do this part normally and get exactly 14 portals at the end).

* 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.

** Edge through again and shoot a portal onto the floor of 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.

* In the final room, put a portal at the foot of the victory lift, then step up onto the platform closest to the first portal, and jump through. Maneuver onto the victory lift platform as you fly up through the exit portal.

* 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.

* 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.
