Germ Warfare

Germ Warfare is a 1-player arcade game for the TRS-80 CoCo.

The player controls a small character who moves laterally at the bottom of the screen and fires vertically forwards. Enemy germs move at 45 degree angles towards the bottom of the screen, and the player must zap them before they reach the bottom and infect the host. When 8 germs reach the bottom, it's game over. The game tracks how many germs have been destroyed, and when all enemies on the screen have been zapped, a new set of baddies appear.
