Description

The earth is under attack by Unidentified Rotating Objects (U.R.O.'s). You are our only line of defense.
Your ship is out of ammo. You can only use your shield, but when you hit an U.R.O. you're shield is down, and it takes some time to recharge. Don't get hit when your shield is down.
You are our only hope. Can you save the earth?
