I scrounged around and found the last figure of the Street Violence blister set I owned, a guy who I guess is supposed to look like Rob Zombie or something. Since I'm Robb, I decided to go with "Rufus" instead. Rufus is armed with a grenade, a knife, a gun, and a drum-fed shotgun. That's a pretty solid kit. Maybe it is the gut and the big belt buckle, but he's got a good "survivor" vibe going for him.
In my inventory of the miniatures I have that might work in this range, I discovered I only had about a dozen zombies, and they are all the Wargames Factory ones. So I ordered a horde of new miniatures from Zombiesmith on Black Friday (he had a sale, 18% off). It might be a while before they get here, but in the meantime I have a few more I can be working on.
