User Summary An overhead view shooter, two versions. One survive wave after wave of zombies on your own, with nothing but weapons as you gather them. In the second you begin the game with a barricade and a number of high powered weapons. You have the ability to upgrade this area as time goes on, and to get out and do some killing yourself. You will need to leave the security of the base to collect weapons as they fall, or your base will be steadily demolished, and you will lack resources to rebuild.
