Prototype is not, as the name implies, the birth of a new genre, but rather the next in an indirect line of open-world games from developer Radical Entertainment. Building upon its past releases like The Simpsons Hit & Run, Hulk: Ultimate Destruction and Scarface -- and seemingly borrowing "jump 30 stories"-like elements from Realtime World's more recent Crackdown -- Radical has chosen New York City as its sandbox and a shape-shifting mystery man as its hero. There'll be a conspiracy to uncover and, of course, a lot of ass kicking.
Publisher Sierra expects Prototype next summer on Xbox 360, PC, and PlayStation 3 (where Sierra will have to come up with a marketing strategy to distinguish its game from Sucker Punch's inFamous).
