Sierra Entertainment puts players in the shoes of a genetically mutated shape-shifter in its latest video game. Developed by Radical Entertainment, Prototype is a sandbox action game which revolves around Alex, a shape-shifter who must piece together his history after waking up without a memory. Exploring a virus-affected city, Alex must face off against mutated civilians and soldiers from Project Blackwatch. Players will have the ability to consume the biomass of their victims, gaining access to their memories, experiences and physical forms. Over time Alex will be able to gain new attacks and abilities. The game is heading to PlayStation 3, Xbox 360 and PC, and is currently scheduled for a winter release.
