OpenMoHAA is an attempt at creating a free, open-source
game engine capable of running Medal of Honor: Allied Assault content (in much the same way that
OpenTTD runs Transport Tycoon Deluxe or
Free in the Dark runs Alone in the Dark), technically superior to the original one by improving security, stability and adding features. It's not a patch, in fact, it has little to do with the original at all, apart from the functionality, which it will try to immitate as closely as possible. It will be built almost from scratch upon the rock-solid codebase of
ioquake3.
Why?
Because the original game imposes severe limitations on modders, preventing some wonderful ideas from coming true ever since the game was released. Because the original game is buggy as hell.
What for?
So that the game experience is better. So that modders can do things that were considered impossible. So that server administrators are spared at least some of the pain of maintaining a good server.
How?
By reinventing the wheel - that is, modifying the Quake III source code to produce a game that looks, plays and feels exactly like MoHAA. By preventing bugs and glitches. By adding server administration tools. By improving the visual quality of the game through the use of new technology (full-screen anti-aliasing, possibly real dynamic lighting).
The project is housed at
.map for MoHAA. A
dedicated forum section has been created, where you can follow OpenMoHAA's development.
We've already had some significant success with it - preliminary support for MoHAA's maps has been added and works.

Screenshots follow below, details available in
this thread.
We hope it will help breathe some new life into this great game and bring back at least some of those who have left the community!
