You are sent out into the desert on a diversion mission. You must survive enemy attack for six days until main forces will take over. Defend your desert position for six long days.
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.
