Peaceful days, that you may possibly remember yet, are definitely over. These days are full of chaos and cruelty - the zombie dayz. Zombies have invaded our planet, and last few brave men are trying to hold them off. War fronts are spread all over the world, from icy tundras to arid deserts. How you decide? Will you help your own people, or will you join the side of evil represented by physically enhanced zombies. Zombirs are attacking you everywhere, so be prepared. Have fun.
