Antichamber review. Classic Game Room presents a CGR Undertow review of Antichamber for PC developed by Demruth and published by Demruth. Antichamber is an exercise of cognitive abilities -- the attention, memory, learning, and decision making parts of the brain -- not just because it's about problem and puzzle solving, but because Antichamber takes what you think you know about interacting with reality and turns it on its side, and then you must react and adapt to a new way of thinking. You'll soon learn that what you first thought was an optical illusion, is not -- what you see is what you get -- Antichamber just operates in a realm outside the norm. That's what matters most in Antichamber: the unparalleled manner in which it embodies abstract concepts through both aesthetic stimuli and cognitive problem solving, the likes of which have never really been seen before. Antichamber takes us somewhere unique that allows and encourages the mind to think differently; and in the process, Antichamber becomes something special. This video review features video gameplay footage of Antichamber for PC and audio commentary from Classic Game Room's Steve.
