Astrosmash is a space-shooter game of its era and involves shooting bombs, asteroids, missiles and flying saucers. It is somewhat similar to the game Asteroids in that most of the target objects are rocks that break apart into smaller pieces when shot, and the player can enter "hyperspace" as an evasive maneuver and be transported to a random position on the screen; however, the player's cannon is more akin to that in Space Invaders as it is situated on a planetary surface and thus can only move from side to side.
