OpenOMF

Open Source Remake of One Must Fall 2097

Experience the legendary 1994 mech fighting game on modern systems. Cross-platform, enhanced networking, and faithful to the original.

About

One Must Fall 2097 is a mech fighting game developed by Diversions Entertainment and published by Epic MegaGames in 1994. Players pilot giant robots called HARs across 10 pilots, 11 mechs, and a tournament mode with upgradeable robots. It was later released as freeware.

OpenOMF is an open-source remake — a ground-up C reimplementation of the engine that uses the original game's data files and runs natively on Linux, Windows, and macOS. Multiplayer uses rollback netcode over UDP, replacing the original IPX/modem connections. Most game modes are implemented, including the tournament mode.
