Man kills zombie horde, only to discover that zombies are people on the inside. Seriously, I think this dude was high on something that made him think these people really were zombies, leading him to cruise by his house, pick up his zombie killing gear, and come back to blow the crap out of some zombie communist sons of bitches.
Um, not that I have any zombie killing gear stored up.
...don't look at me like that you zombie-lover...
*unpacks the gear*
