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.
Eliminate the invading force intent on taking Space Station Xorbe in Earth's orbit. If the station is captured then it'll become a staging ground for the invasion of Earth itself. You got a huge arsenal of weapons and defensive mechanisms to stop them.
Drive a single tank against the enemy army. Defend your teleporter and prevent enemy units from escaping through it. Do not leave the battlefield or you will be terminated.
Shoot the incoming enemies to protect your base. Collect weapons and turrets that automatically fire on the incoming missiles. Push the turrets around the battlefield to take advantage of their range and abilities.
