A Gamer, a Girl, a Mad Scientist and an Alien are all that stands between 6 billion zombies and the world's supply of delicious, supple brains. All Zombies Must Die! drops up to four players into the town of Deadhill, where they must blast their way through ranks of brain hungry monsters with a variety of weaponry while completing quests served up by the game's insane storyline. doublesix is combining elements of action and role-playing, including character levelling, weapons crafting and numerous quests. The graphics reflect the silly yet sinister nature of the gameplay with a bright, comic style.
