Videogamer writes: "Crackdown plus Dead Rising equals Prototype. That might be simplifying matters somewhat, but you get the idea.
You play Alex Mercer, a hoodie-loving shape shifter who has complete control over his DNA. Like the hoodies that enjoy staring out old people on Streatham High Road, Alex is partial to the odd mood swing. Who can blame him? Without any memory of his past he's fuelled by a burning sense of revenge, and takes it out on the military and the Infected, Prototype's zombie-esque bad-guys that roam the streets of New York. This three-way war, the army versus the Infected versus Alex, is a constant and evolving meta-game in of itself."
