Sierra Entertainment has released a video dev diary and four new screenshots from Prototype, a completely new kind of open-world game which 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. In the works at Radical Entertainment, Prototype will be available this summer, for PC, Xbox 360 and PS3.
