Once Heller consumes a person, he can take their identity, as well as read their memories. You will have to complete missions in different areas of the New York Zoo, which has areas that are covered with viral infection, in order to find Mercer. Having the protagonist from the first game as the antagonist for Prototype 2 gives it a nice twist. The target of your vengeance is no other than Alex Mercer. As Sergeant James Heller, you must find the man who developed a deadly virus that killed your family, and return the favor. Your character, Sgt James Heller, has the ability to shape-shift and is after the person he holds responsible for the death of his family. With all these great features combined, this could very well be the best sandbox game currently available. It possesses a great story line a character that you feel connected with, and improved gameplay.
Prototype 2 turned out much better than many people thought it would.
