One Must Fall: Battlegrounds (video game)

One Must Fall: Battlegrounds is a fighting game for Microsoft Windows. Developed by Diversions Entertainment and co-published in December 2003 by Diversions Publishing and Trisynergy Inc. following nearly 7 years of development, One Must Fall: Battlegrounds brought the One Must Fall series into a second installment released in an age where the gaming world expected graphics and gameplay in three dimensions with internet gameplay an integral portion of the offering.

Battlegrounds started development as a sequel to the popular shareware title One Must Fall: 2097, playing in a side scrolling manner with two opponents facing each other. At the time, Rob Elam saw the opportunity in the Unreal Engine then in development by 2097 publisher Epic Mega Games. At the time, Epic was not yet at a point where they were willing to examine licensing the engine or developing the Unreal Engine for third party use and so a joint decision was reached whereby Rob Elam left to develop a new game engine.
