From the introduction: YOU ARE SURVIVORS STILL ALIVE AFTER A ZOMBIE PLAGUE SWEPT THROUGH THE WORLD! You’re long past hoping to find a safe haven-- those places where the first to fall. Now you are just trying to stay alive, if those damn zombies can stay away. Use GRIT to hold the door between you and the undead hordes; or use GUTS to open that door and face them head on. Either way, it’ll take a lot of both to survive!
