Brad Zoom takes on Brain Eater from Purple Planet, in this tribute to vintage vintage games, primarily Galaxians.
There are 75 levels accessible by password.
The player controls a spaceship at the bottom of the screen, firing at the aliens arranged in various formations.
Movement can occur up and down as well as right and left.
At regular intervals an alien will emerge from the main group and descend to the player-controlled spaceship. Other asteroid levels that divide when hit or a single “boss” alien.
Aliens with green eyes release upgrades like improved weapons, shields and bombs.
There is only one life available.
