Players will take control of anti-hero Alex Mercer, who wakes up in a mysterious laboratory as an experiment with no memory of his past. The world of Prototype is engulfed in a three-way conflict between the military, a mutated viral epidemic, and Mercer -- who has become a weapon in his own right. The whole game is built around the idea of "weaponizing" yourself. Mercer can absorb his enemies, taking on their memories, appearance, and abilities. Consume a helicopter pilot, and you'll learn how to fly a helicopter.
