Artificial Studios and Immersion Games have today announced the availability of CellFactor: Revolution via free download, of course you'll need an Ageia PhysX card in order to play it in it's entirety. You can grab the 859mb download at Fileplanet or Filefront.

"This is has been an exciting and very rewarding project that pushed boundaries both artistically and technically," said Julian Castillo, art director, lead designer and co-owner of Immersion Games. "By incorporating the PhysX processor into the game, we’ve introduced a whole new range of gameplay possibilities. We’re eagerly anticipating stories of players favorite kills."

Jeremy Stieglitz, president of Artificial Studios added, "CellFactor: Revolution is a new kind of competitive first person shooter, which emphasizes massive physical interactivity to take down your opponents. I’m very excited that gamers can now experience this intense action whether it’s at a LAN party, fighting AI bots or designing new environments with the modding tools."

CellFactor: Revolution caters to players with and without the AGEIA PhysX card. The game automatically detects systems with a PhysX card, offering players the option to progress through a single-player campaign mode that includes three "extreme PhysX" levels. PhysX users can also challenge humans and AI-enemies in four LAN-based multiplayer modes. The multiplayer skirmish game types support up to eight humans and 10 artificial intelligence controlled enemies, either in a PhysX hardware only, or software only mode. Gamers without a PhysX processor can play two levels in skirmish modes or choose to install the processor to enable the full game experience.

"The sheer entertainment value of PhysX in CellFactor: Revolution cannot be overstated," said Manju Hegde, CEO of AGEIA Technologies, Inc. "We’re honored to work with cutting-edge development teams who have used PhysX technology as the backbone for this fun and original experience, now available for the masses."
