Be warned, this Prototype 2 trailer contains major spoilers for Prototype 1. Very major spoilers. In fact, ALL of the spoilers. The entire plot is laid bare, and acts as a set up for the rise of the new similar-but-angrier protagonist, Sergeant James Heller, who is coincidentally the star of a batch of new Prototype 2 screenshots. See his many mutant arms doing terrible things to tanks, helicopters and men in armoured battlesuits below.
