Apr 18, 2011
In this game, you can…
- hit a chapter title that literally says "this is the part where he kills you" as the game turns it into a set-piece
- bounce across chambers with repulsion gel, build insane speed with propulsion gel, then paint walls to make new portal surfaces
- play co-op where each robot has its own portal gun, and your solution can break the bridge your partner is standing on
- wake up from long-term stasis, get guided by a friendly AI, and then have the main villain come back online
- use portals to redirect lasers, light bridges, and tractor beams through moving machinery to power your way forward
- chain portals to fling yourself over pits, launch cubes onto buttons, and keep extending the same trick into bigger gaps
- replay co-op stages for least time and least portals, racing friends as they knock you off the leaderboard
- drop into community-made test chambers and keep getting brand-new puzzles long after the story ends
