Last Battle is a defense game in which you must defend four different bases, each over a span of ten days. Shoot soldiers, trucks, and tanks to prevent them from causing serious damage to the base. As you kill enemies, you will gain money. At the end of each day, you can spend your money on new guns, weapon upgrades, walls, assistance, and extras. The game saves your progress after you successfully defend a base for ten days. If the enemy manages to destroy your base, you will have to return to day one.
