Space Strike is a 1982 fixed shooter video game for IBM PC compatibles programmed by Michael Abrash and published by Datamost.

As in Space Invaders, the player controls a small mobile firing platform that he moves side to side along the bottom of the screen.

Waves of aliens attack from above, sweeping back and forth and slowly descending.

Barriers provide cover for the player, but are degraded by weapons fire both from above and from below.

This doesn't change the fact that it is a well programmed, error-free game.
