Reactor is a raster video arcade game released in 1982 by Gottlieb. The object of the game is to cool down the reactor core without being hurled by magnetism and repulsion by enemy swarms of nuclear particles. The game was ported to the Atari 2600 by Charlie Heath and published by Parker Brothers the same year.
Reactor was developed by Tim Skelly, who previously designed and programmed a series of vector graphics arcade games for Cinematronics, including Rip-Off. It was the first arcade game to credit the developer on the game’s title screen.
