Solaris is considered a sequel to Star Raiders as both were programmed by Douglas Neubauer and feature the enemy race known as the Zylons.


The Zylons have return and threaten the galaxy. Piloting your StarCruiser you must engage the enemy fleet, defend Federation planets, and locate the lost planet of Solaris.


The game plays out in two modes. The Galactic Scanner shows a map of the currently occupied quadrant. There are sixteen quadrants with 48 sectors each. From here the player navigates their StarCruiser to the Zylon fleets. When an enemy unit is selected the game changes to a third person view where the player shoots down enemy ships. As the player progresses through the game he will need to land on friendly planets to refuel the Star Cruiser. The ultimate goal of the game is to find Solaris and rescue the planet's colonists.


The game was originally called The Last Starfighter, as it was in development at the same time as the Atari 5200 game based on the movie of the same name, which became Star Raiders II on the Atari 8-bit home computers.
