CellFactor: Revolution is 100% free for everyone and features extended content for PhysX accelerator owners in the form of a progressive single-player campaign and three additional extreme physics levels. In addition to the more traditional weapons load-out, CellFactor: Revolution offers the ability to use the various environmental hazards as a weapon. Don't feel like the sniper rifle gets the point across? You can use your PSI powers to shove an entire lava stream at your enemies or pick them up and hold them under a stream of toxic waste which streams realistically over their body inflicting massive damage - the possibilities are nearly limitless!
