December 20th,2012. The month before the massive asteroid is due to strike the earth the zombies started rising out of the underworld,trying to take over the earth once we're gone.The army was called in to settle this problem,and have set up base fairly close to the main zombie graveyard. Now it's the day before the end of the world and the zombies are finally starting to retreat. With the others either dead or eaten,you are one of the last surviving soldiers in the bases trying to fend off the last of the zombies. You have just finished killing one with your trusty knife,when suddenly a hoard of those disgusting creatures rushes toward you and your buddies. Well? What are you waiting for? Pull out your guns and fight!!!
