The people of Earth have formed a colony and built an android army to defend this colony against alien invaders. Unfortunately, the Cyber-Lip Master Defense Computer decides to use this army to attack the humans in the colony. With a legion of robotic troops marching into battle against the colony, the humans are left to fend for themselves. Two soldiers have been assigned the task of taking on the mechanical army with the hopes and prayers of all humanity on their shoulders.
The gameplay is intense as you fight your way through several areas, defeating a boss at the end of each one. You can pick up various weapons along the way to use against the invaders. Destroying certain enemies rewards you with "core bots", which are rings that surround you, and when they touch the invaders, they are destroyed. Time is against you, as losing a life occurs when time expires.
Between levels, an elevator allows you to move in any direction: up or down. If you wait too long to make a selection, you will automatically be placed on the "Danger" mission.
