Force Field
Description
Force Field is a 1-player arcade game for the TRS-80 CoCo.
The aliens are attacking Earth's force field. The player controls a small spaceship that moves laterally at the bottom of the screen, protected by a force field. The ship can fire vertically upwards. Five alien vessels appear at a time, and when an alien touches the shield 1% of total power is lost. When all aliens are destroyed, an identical new wave of enemies appear.
