Zombie Cafe

Zombie Cafe is a free to play game from Beeline Interactive (a subsidiary from Capcom) released in 2011 for the Apple iOS. It can be downloaded for free at the app store, but charges real money for additional in-app content.

Summary
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.

Mega Man Collaboration
In 2014, from December 26 to December 31, an event was held in the Japanese version of the game where Mega Man content was available during its duration.
