Antichamber, the mind-bending puzzler, has now launched on Steam. The game is all about playing tricks with your mind -- whether that be in the form of perspective, logic, or gaming conventions. Antichamber looks like the perfect 3D platforming/puzzler for those who don't like them, as there is no failure in it and you'll eventually come across a solution through trial and error. Its normal price is $20, but until Feb. 6, it will be knocked down to $15 -- bringing the price to a very reasonable level for those curious about trying it, but not quite willing to spend $20 on it.
