Select a traditional first person view or choose the third person view to play this 3D action game in a new varied perspective. Third person view removes point-of-view limitations and let you jump and see more of your environment, crouch more easily, and do things you'd do in an arcade platform game. Choose among 3 distinct characters, each with its own unique gameplay style, strengths, weapons and storyline for 3 different playing experiences. An intelligent AI creates challenging game play with cunning mutated enemies who become smarter and even interact amongst themselves.
