PROTOTYPE for Xbox 360 tells the story of Alex Mercer - a man haunted by his past, fighting a secret war in New York City. As the action spirals out of control, a conspiracy tied to his origins threatens the future of mankind itself. Mercer's amazing shapeshifting powers allow him to become an exact replica and steal the skills or powers of anyone who crosses his path.

PROTOTYPE on Xbox 360 is a completely new kind of open-world/action game, featuring a rich storyline filled with deadly shape-shifting action, 'Deceive or Destroy' gameplay, and a conspiracy 40 years in the making. In PROTOTYPE for Xbox 360, players take control of Alex Mercer - a dark, genetically mutated shape-shifter with no memory of his past, hell-bent on solving the mystery of his existence as he tears through a densely populated New York City moving with Parkour-style fluidity and consuming anything that gets in his way. 'Deceive or Destroy' gameplay allows gamers the choice to either blend in with the population and covertly progress through the story, or fully unleash Alex's powers, and move through New York City like a walking slaughterhouse, taking control of military vehicles, and causing destruction at every turn.
