Gingerbread zombies inspired by Left 4 Dead 2

Found on the net, these gingerbread zombies inspired by the terrifying and brilliant new Left 4 Dead 2 game. Anyone know who made these or where they come from? Whomever it is deserves a medal, some ammo, an incendiary grenade, some boomer bile and a BFG.

Update: Maxious knows who made it!: He writes in the comments, YellowPoison and his mom on reddit did it
