Lifelike soundscapes developed by Robin Arnott and an ambient soundtrack composed by Siddhartha Barnhoorn.

Mind-bending challenges that will subvert your expectations at every twist and turn.

Antichamber was also supported by the Indie Fund. Several years in the making, Antichamber received over 25 awards and honors throughout its development, in major competitions including the Independent Games Festival, the PAX10, IndieCade and Make Something Unreal. 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. However the 2nd September 2009 UT3 Mod was not so I had to find it after some digging on the internet.Antichamber is a mind-bending psychological exploration game where nothing can be taken for granted. Luckily, the 2010 demo and the final UT3 mod release were saved to. Originally, the mod was available from Alexander Bruce's website,, which now redirects to. This version of the game is no longer obtainable except for one or two obscure mirrors. Overall, the map was mostly the same with a few less rooms as well as different puzzles because of the limitations of a UT3 mod. Many of the puzzles changed between Hazard and Antichamber, although most of these changes included additions and simplifications. The gun model was completely different, as pictured in one of the Dev Rooms of Antichamber this gun was a washed out version of the Link Gun from UT3.

Hazard was an Unreal Tournament 3 (UT3) mod.

Hazard: The Journey of Life was the original name for Antichamber when it was in the alpha testing stages.
