Based on CellFactor: Combat Training, a technology demonstration created by Artificial Studios in conjunction with Immersion Games to showcase the capabilities of AGEIA's PhysX processor, CellFactor: Revolution is an action-packed first-person shooter that takes advantage of the capabilities of the dedicated AGEIA PhysX processor. CellFactor: Revolution was intended to hit the store shelves this Spring, but the official website has a counter which indicates that the game will be released for free on May 8th.
