Superman is an action-adventure video game programmed by John Dunn for the Atari Video Computer System and released in 1979 by Atari, Inc. The player controls Superman, whose quest is to explore an open-ended environment to find three pieces of a bridge that was destroyed by Lex Luthor, capture Luthor and his criminal gang, and return to the Daily Planet building. The game world is populated by antagonists such as a helicopter that re-arranges the bridge pieces and roving kryptonite satellites that cause Superman to revert into Clark Kent.
