Activision has announced two additional US pre-order incentives for Prototype 2 through Amazon and Best Buy.
Those who pre-order through the online retailer will receive and instant download code for the first issue of the Prototype 2 comic The Anchor. It details the "downward spiral" of Alex Mercer, and was created by Dark Horse Comics.
Choosing Best Buy will net you a Prototype 2 steelbook case only available in the US and while supplies last. This is in addition to the previously announced Hardened Steel Vehicle Armor upgrade available through the retailer.
Players who pre-order will also secure access to the RADNET Edition content, a collection of 55 free in-game Events, Challenges, Avatar Items, Dynamic Themes and Behind-the-Scenes videos, bonus Mutations for the main campaign as well as an Alex Mercer playable skin, delivered for seven weeks following the games launch.
Prototype 2 releases in the US on April 24 and in Europe on April 26 for PS3 and Xbox 360. The PC version will be released July 24.
