If you get the chance to see the Outpost prequel comic packaged with the iPhone game, you might notice a sneak peak at the new villains of the third movie in the editorial feature.
The Berzerkers are Nazi zombies bred for war. No shambling corpses, these guys are undead velociraptors in uniform.
This is my pre production painting of the Berzerker from last year. In the new movie out in 2013, the Berzerker will be played by mixed martial artist, James (The Colossus) Thomson.
