Space Intruders

Space Intruders is a 1-player Space Invaders game for the TRS-80 CoCo.

The player controls a small ship that moves laterally at the bottom of the screen and fires vertically forwards. The player must destroy waves of attacking aliens, which move horizontally across the screen, reach the edge, move down, and reverse direction. The player must avoid alien fire, and destroy all enemy aliens before they reach the bottom of the screen. The player starts with 3 lives, and shields offer temporary protection for the player.
