From the "first look" preview:
"Let me introduce you to Alex Mercer; who is a shadowy character, somewhat like a modern version of Altair from Assassins Creed. Alex wakes up on an autopsy table with two scientist types about to cut him open. He has no memories of who he is or how he got there. He promptly escapes and while doing so, discovers he has a wealth of powers at his disposal. Alex then uses his newfound powers to re-discover his past as he attempts to find out what happened to him. Alex is lead to a company called Genrek, which he used to be scientist for. Genrek are a medicine company who have created a virus that's spreading through the population, mutating any human DNA it comes into contact with. Alex must choose to help the human race or leave them to the ravages of the virus. The game goes by the name Prototype."
