A new zombie game has risen from the grave called Battle Girls! The game features cute high school girls chibified, story mode, random zombies, costumes, endless zombie mode, and more. I think you're supposed to recruit, mix, and combine zombies in this game. Sounds kind of funky, yeah!? They are pretty honest with their zombie unit count, mentioning that they are only offering 50 different kinds of zombies, so little. Hope it gets updated often! The game has a decent rating so far in Google Play market, but not many reviews yet.
