Invasion Strike
Description
Invasion Strike is a 1-player arcade game for the TRS-80.
The player controls a small ship on the bottom of the screen, which moves horizontally and fires vertically. An alien spaceship moves in horizontal rows from left to right, moving down one row each time. The player attempts to shoot the alien ship as it moves by. If the alien vessel reaches its home, the player loses a vessel. Each time the player shoots an alien vessel, the alien's home moves closer to its starting point. If the alien reaches its home 3 times, it's game over.
