Evil Aliens attacked our planet and you should stop them. You are the only hope for all Earth citizens. Your brave soldiers and powerful tanks waiting for your commands to smash those evildoers.
Shoot enemies down and advance to the next level. As the game progresses more weapons become available and you will encounter more challenging enemies.
Your forces were out on a routine patrol and the undead were suddenly everywhere! Your forces were badly depleted in the conflict thus you must continue to do your job and keep the undead population under control until a solution can be found.
