Antichamber is a mind-bending psychological exploration game where nothing can be taken for granted. Discover an Escher-like world where hallways wrap around upon each other, spaces reconfigure themselves, and accomplishing the impossible may just be the only way forward.
This game uses an evolutionary algorithm to generate platformer levels. The goal is to create the hardest platformer levels possible (which are still winnable). A central online server is used to breed together the most difficult levels and propagate them to other, future players.
