What it is

OpenMoHAA is an open-source project aimed at preserving and enhancing Medal of Honor: Allied Assault (including the Spearhead and Breakthrough expansions) by providing more features and bugfixes across modern platforms and architectures. Powered by ioquake3 and the F.A.K.K SDK, it offers full compatibility with the original game (assets, scripts and multiplayer), better support for modern systems, Linux, Windows and macOS, single-player and multiplayer, all fixes from Spearhead 2.15 and Breakthrough 2.40b, and extras such as bots and a ban system.

The project itself says it has not reached version 1.0.0 yet and is like a beta build from the golden age of LAN parties. It is not affiliated with or endorsed by Electronic Arts. You need the files from your copy of the game. GigaROM does not host the game; the download comes from the official page.
