It's a Prototype 2 double-whammy now, as firstly, Activision and Radical have announced a couple of US pre-order bonuses for Amazon and Best Buy, and secondly, there's some screens and videos showing new hero Sgt. James Heller smashing up tanks and helicopter gunships.

Pre-ordering Prototype 2 at Amazon.com will let you get your tendrils on a code to download the Prototype 2: The Anchor comic book from Dark Horse, which details the downward spiral of Prototype 1's Alex Mercer, who also serves as Prototype 2's antagonist. A pre-order from Best Buy meanwhile, will bag you an exclusive steelbook case edition of the game, as well as the Hardened Steel Vehicle Armour upgrade.

And of course, all pre-orders will earn you the Prototype 2 RADNET Edition, which offers 55 pieces of DLC that'll be released across seven weeks post-launch. Check out the trailers and screenshots below to see Heller in action, destroying military vehicles, then look out for Prototype 2 this April.
