One Must Fall: 2097 is a fighting video game for all IBM-compatible computers on DOS, programmed by Diversions Entertainment, published by Epic MegaGames and released in October 1994.

One Must Fall: 2097 replaces the human combatants typical of contemporary fighter video games with large Human Assisted Robots (HAR). These HARs are piloted through a physical and mental link to the human pilots; however, this is merely a plot concept and is never shown on-screen.
