Zombie Cafe (ゾンビカフェ) is a free to play game by Beeline Interactive released in 2011 for iPod, iPad, iPhone, and MacBook. It can be download for free at the app store, but charges real money for additional in-app content.
It's hard to find good help, thus a café owner partnered with an evil corporation to use zombies as free labor to build a café empire. Customers can be infected to become eternal zombie slaves by using a Toxin, giving the chef an advantage over the neighbouring "human" cafés. Like a normal café, prepare food with all kinds of recipes, direct the (zombie) workers, decorate the place, manage supplies, and earn money to improve the café. However, if the zombies work too hard they'll get tired and try to eat customers. If the competition gets too fierce, the chef can always direct the zombies to attack a neighboring café and steal their secret recipes and money.
Players can connect with their Facebook friends to form a franchise, ordering food, collecting fees, and sharing recipes.
