Love, love, love this! I agree there would be a recoil on the gun, but really, how can you get all this in a picture? Also with the idea that the character's going to be bit? Who knows what's outside the picture that we can't see? Maybe he's got some other "non-walkers" (LOL!) who've got his back? Maybe he's got another bullet ready for the biter near his stomach? As a chick...most guys don't think we like this stuff...I'm the perfect geek for this, though. Love "The Walking Dead", Romero, Resident Evil. There could always be a follow up. FYI...I think he'll live. Or as Arnie said in Terminator 2 after shooting the guard in the knee "He'll live."
Ehh... by the image it looks like he might not have a choice. I mean one zombie already really on him(front), one behind looking like it's already gunning for his shoulder, and it'd be hard to get all those zombies just in time. XD
