If your brain has recovered from Antichamber, you may want to subject it to the latest footage of Parallax, which turns the burgeoning 'first-person mind-f**k' genre on its head. This trailer shows off the game's unhinged definition of gravity, which doesn't so much obey the laws of physics as pull funny faces while they're trying to go about their business. Parallax is shaping up to be an unchained version of Antichamber, in other words, so there's every reason to be very excited about this upcoming release. Have your O, M and G keys to hand, as you'll need them after witnessing the following video.
