Based on the Atari Force comic book series from DC Comics, the Liberator video game features trackball, fire button, and shield button controls in game play. You will operate four spaceships, comprising the Atari Force, to aim attacks at the enemy missile bases as you circle their planet. Prepare for strong resistance though: enemy starballs and MIRVs will attempt to block your attacks and their bases can depart from land to transform into satellites, shooting their weapons at close range. When the Atari Force advances to the next level, a new planet will appear. In the face of excessive counterattack, you can utilize the Atari Shield to protect your force up to four times per level. Atari created and manufactured Liberator in 1982.
