Britxbox's Jasper Kashap writes: "Rarely does a game that started life as a tech demo for a PC physics card suddenly appear on the Live Arcade, but CellFactor, with the rather daft subtitle Psychokinetic Wars, is that game. A physics heavy first person shooter that owes a lot to the likes of Unreal Tournament and Quake III Arena.
What sets CellFactor apart from most FPSs is the choice of 3 distinct classes to play as; Bishop, Guardian and Black Op, each with their own collection of super powers. The Bishop can fly, psychically throw individual or multiple objects at once, block projectiles with a psychic shield and flash-stun enemies. She uses her own versions of the games weapons, which are picked up as normal but fired from the fingertips or hand. The Guardian ditches all the physics malarkey and can instead dodge, dual wield and super jump. He can also use his speed run to instantly kill or quickly navigate the map."
