Astrorock is a 1996 personal computer game for systems with Windows 95 and newer. In the year 9999, the bash of the millennium is about to be invaded by evil mutant aliens. Zep Nepher (a possible pop culture reference to Led Zeppelin) needs the player's hope to restore rock and roll music to the interstellar vastness. Bad guys will have to be defeated in the far off Bee-Gee cluster (a pop culture reference to the classic band, the Bee Gees). The player gets to use an awesome display of fire power. While its beginning levels are a modern adaptation of Asteroids, the later levels deviate from this concept considerably.
