Sierra has released
a trailer for Prototype, an upcoming open-world third-person action game by
Radical Entertainment. The game is slated release in the summer of 2008 for the
Playstation 3, Xbox 360 and PC platforms. The player controls the character of
amnesiac Alex Mercer in New York, with freedom similar to that of Hulk: Ultimate
Destruction, in which the player can visit most locations and interact with the
environment while not engaged in missions. Alex will clash with the military's
Black Watch Special Forces and the effects of a mutated viral epidemic as he
works to discover the secrets of his past.
