GameSpy - We've all encountered games with mechanics that are difficult to describe, but when you find a game where even the concept is difficult to put into words, you know you've come across something singular. Is Antichamber a puzzler with platforming elements? A philosophical examination of the boundaries of physical laws? A recreation of what a prison designed by Escher might have looked like? The answer, of course, is that it's a mixture of all of these, and while the result is a game that's not easily described, it's also one that's easily recommended if you're a fan of games that hide plentiful moments of satisfaction behind an array of fiendishly perplexing puzzles.
