APOCALYPSE PARTY (itch)

It started as a nice game of paintball for a birthday party, but through some kind of sick joke, all players became zombies from eating contaminated meat. All players that is, except for one man. Being a vegetarian he hadn't touched the stuff. He tried to escape but to his horror the exit was locked. He still had five more minutes until the paintball session was over and the doors unlocked. The only thing stopping the zombies from overpowering him was the lights. As long as there was light, the zombies were weak. Armed with nothing but his high power paintball gun, our protagonist defends the generator that powers the lights . . .
