REACTOR: 1982 GOTTLIEB HIGHLY SOUGHT AFTER RARE GAME

The player uses his ship to deflect enemy particles into the Reactor wall without getting deflected into the wall himself. Meanwhile, the Reactor core is constantly expanding unless the player deflects the enemy particles into the sets of control rods located on the screen and in later levels turns into a vortex which can "suck" the player's ship in. The player can use energy to make the deflections more forceful or use decoys to fool the enemy particles.
