Today’s friend is tomorrow’s enemy in new Prototype 2 trailer

Prototype 2 pits the first game’s Alex Mercer against newbie Heller. The twist? You’re not Mercer anymore; he’s the villain in this one and it’s Heller’s job to take him down. The video above explains why the developers took this twist, accompanied by some rather unpleasant new gameplay footage. And by unpleasant we’re talking about the things going on in the video, not the state of the game, which looks rather promising.

Shame we still have to wait until 2012 for this one, then.
