OpenOMF is an Open Source remake of "One Must Fall 2097" by Diversions Entertainment. Since the original DOS game from 1994 uses IPX networking and is a pain to set up, the community needed a better solution to keep playing the game we love. Together with networking, we try to make it easier to play One Must Fall in its original glory on multiple platforms (Linux, Mac OSX, Windows, BSD to name a few).

OMF2097 hold a special place in my heart. As a kid, it was my first "serious" game (and the only fighting game I ever enjoyed), and I played the heck out of the demo. Then I found out there was more game to be had! With my dad's help we ordered the full version over the phone. When that arrived in the mail, oh man, my excitement was through the roof.
I also recall being very excited over a 3D sequel that never materialized.
I am so prepared to destroy all my fond memories of this game by trying to get it running on the Steam Deck.
In my mind the original has always been in 3D and thus even more impressive on DOS.
Pre-rendered 3D models as 2D sprites. Looked quite cool back then, but IMHO aged very poorly.
