zombie apocalypse

Government experiments with chemicals came with a huge results that ultimately wiped half of the human race into zombies, or dead. Most cities are avoided if they are to continue to survive and shops are abandoned. Now, the government secret program has gone rogue and decided to find a cure by testing zombies in their labs safely underground but there's one thing they have forgotten to get rid of: the human experiments for military purposes that have escaped and hid across the American continent. Only these humans can get the cure to try to save the human race... for they have special abilities.

The kind of characters people can choose is a military human experiment or a wandering human survivor.
