Edit: The video is below now.
Perhaps not the most catchy of names, Nexuiz has just been announced as receiving a publishing deal from THQ Partners and Machinima. And thus into the public gaze it heads. IllFonic's CryEngine 3 game is an FPS "reimagining" of the game's previous incarnation when released by Alien Trap in 2005. Then it was intended to be a GPL shooter, free to play, and free software, available on PC, Mac and Linux. Original designer, Forest Hale, has moved over to IllFonic for the project, currently suggested to cost $10 on release, which we can probably assume won't be equally as Free with Crytek's code underneath. And it's a properly mind-bending concept.
Using something called Dynamic Mutators, which allow the up-to-eight players to muck around with an arena's physics. What they are, I'm not yet aware, and I confess to not having played the original.
IllFonic seem a strange bunch, currently also making (the troubling looking) Ghetto Golf, and describing their games section as "Upcoming Shit". Which doesn't perhaps convey quite the image one might want from a developer.
The game should be out on Steam early next year.
