Sierra has officially launched ‘Prototype’ website. It is still in development for PS3, PC and the Xbox360.  A little about Prototype the game, it is developed by Radical Entertainment, a critically acclaimed developer of open-world games, PROTOTYPE 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.
