Survivors of Undead and Flesh

You were just living your life. Rumors started about people biting other people and strange flesh growths.

Then the explosions began.

You wake up in a bunker, there was nothing more than a book with you.

Explore the ruined cities, look for ancient relics, and find other survivors out there.

Build up a colony of the survivors. 

This will not be easy as the flesh and zombies are continuing to consume. Infection is inevitable.
