Astro Assembler is a space-faring, top-down, vertically-scrolling, shoot-
em-up. Pilot your spaceship against insurmountable swarms of enemy ships and
asteroid-planted bases. The player’s ship’s offensive weapons attack on 2
planes: The rapid fire laser is effective against flying targets, while firing
also launches missiles at a lower rate of fire that attack ground targets.
There is a plethora of powerups to collect that grant such added capabilities
as more speed, more powerful lasers and missiles, and higher rate of fire. Be
careful, though, because some collectible items are actually powerdowns.

The “Assembler” part of the title refers to sets of specific ship pieces that
the player pursues in the game. These components assemble to create a more
powerful ship with greater offensive and defensive capabilities.
