Zombie Apocolypse

My Zombie Apocolypse game seems to have taken off. I'm making a second one, and I would like to know suggestions for the new one and changes I should make to the original. I'm going to keep a lot of the second one a secret until I release it though

Make it teams, i dont like zombies allying humans it sucks

I completely agree. It should be teams. Humans should not be allying with the things trying to eat them.
