Hmmm... possibly. You could certainly invite him and see. I was also thinking... have you ever played the game Prototype? It's kinda a mutating zombie virus getting loose too. We could add elements of that to it too. Like the Hunters, they're giant, strong really fast monsters. Wicked tank destroyers. I hate it when they gang up on me... anyway they're kool but I also like the way the main character can shift his form. He can turn his arm into a wicked blade, or give himself giant fists like boulders that can smash things, he can fly for short distances and run straight up a building (while carrying a poor innocent victim which he can throw off the top of empire state building... so much fun watching them fly...), he can lift cars and throw them, coat himself in a thick coat of wicked looking armor, turn his arm into a shield, and also turn his arm into a kind of whip which can drag down helicopters. I think it'd be kool if one or maybe all of the agents had those abilities or some of them.
