UNLICENSED GAME This game is an unlicensed version of Tetris (1984). User SummaryAtomic Tetris is a competitive Tetris-like game in which two players compete to last the longest. What makes this game slightly different is that random blocks may appear which provide a means to disrupt one's opponent: clearing a particular brick may reverse the other player's controls, add a strange block to his screen, and so on. There is only a two-player game mode in the DOS edition.
