Changes

The player controls a spaceship with its weapons that he/she uses to blast apart "spores" that connect together to form dangerous aliens. Once formed, the aliens must be obliterated, else, they will destroy the player. Incubators, black boxes with countdown numbers on them, continually release new spores as the game progresses, or, in later levels, give birth to aliens. ==Advertising Blurbs=====Front Cover of Manual===You and your ship have been given a mission. Destroy the aliens before they destroy you! ===Back Cover of Manual===With The Attack Command Module, you command a ship that is cruising the far limits of outer space. The region is infected by spores. Suddenly, an alien emerges. You, as commander, are the only one who can maneuver your shop to avoid the clutches of an alien and fire your missiles.
