Fract is a first-person puzzle game. We like those. We also like things that look insanely awesome, which this does. The beta is out - not quite complete, as is the way of the beta - and quite playable. Well, I say playable, I can't much past the first puzzle, when the world is revealed to be some kind of exploded musical Darwinia. Creator Richard E Flanagan says: "The player is let loose into an abstract world built on sound and structures inspired by electronic music. It’s up to the player to resurrect and revive the long forgotten machinery of this musical world, in order to unlock its’ inner workings!"
So you should probably do that. Here's the beta. And there's a video of it in action below.
