Yeah there are plenty of sandbox games around and GTA 4 is top dog among them. Enter Prototype, you fill the shoes of Alex Mercer, amnesiac but with superhuman strength, speed, agility, durability and healing. The most awesome power he has the ability to absorb the memories, shape and strengths of his fallen enemies and also can reshape his body parts into claws, shields, armour or spikes. To really appreciate the game watch the teaser(above). It would be available for PS3,XBOX360 and PC. There is no word on a release date yet.
