Prototype

Prototype is an open world video game developed by Radical Entertainment and published by Activision. The game was released in North America on June 9, 2009, and in southwestern parts of North America as well as Oceania on June 10, and was released in Europe on June 12.
The game is set in New York City, where a virulent plague is spreading through Manhattan. Those infected are mutated into hideous monsters. The United States Marine Corps, under the command of the black ops organization Blackwatch, is dispatched to contain it. At the center of it is the protagonist, Alex Mercer, a shapeshifter with no memory of his past. Alex has the ability to absorb other individuals, taking on their biomass, memories, experiences, and physical forms. Parallel to the game's storyline is the ability to play the game as a sandbox-style video game giving the player freedom to roam Manhattan.
Many reviewers compared and contrasted it with Infamous, a game released in the previous month by Sucker Punch Productions which features a superhero with developing powers in an open world. However, the gameplay is very similar to The Incredible Hulk: Ultimate Destruction, also by Radical Entertainment.[3]
