As the sheriff of Oakwood, it's your job to protect the village from an impending swarm of zombies! Kill all of the zombies before they destroy the holy altar! Set traps or shoot them down, but don't don't get into close combat or the zombies will maul you. Pick up health kits to give your health bar a boost (top left), money to purchase upgrades after each level, and ammo to gun down your enemies!

Note this game has weird loading issues I found refreshing fixes them.
