Odamex is a free, cross-platform (Mac, Windows, Linux) modification of the Doom engine that allows players to easily join servers dedicated to playing Doom online. The goal of Odamex is to add enhancements to Doom while still retaining that "classic Doom feel" we all know and love about the original game.

Odamex is free software, however a copy of Doom or Doom II is recommended to play it. If you do not own Doom, it can be purchased on Steam. Other alternatives include using Freedoom, or the Shareware version of Doom.

Latest version: 0.7.0

Released: March 27, 2014 :: Updated: March 29, 2014

Git Out of Here!
We've moved to Github. You can check out our repo here:


Some of you might have noticed that the changelog and other web site scripts that relied on SVN have yet to be updated. They will be updated eventually but with no estimated time. Until then you can still see changes on the Github changelog and via #odamex on OFTC.

Have fun kids!

Odamex is Looking for Programming Talent
The Odamex Doom source port is looking for someone that is willing to help with the programming side of the project. Odamex is a Client/Server modification of ZDoom 1.22 with some ZDoom 1.23 code imported in. The project is written in C++ for the client and server and uses SDL 1.2 and SDL_Mixer  1.2 as runtime libraries. The entire project is entirely GPL or GPL compatible as well.

Odamex has several advanced features, including on-the-fly wad changing, the ability to trigger between vanilla Doom and ZDoom physics and nuances, map voting, an optional 32bpp renderer, network packet-based multiplayer demos, and backwards reconciliation netcode optimizations for high latency players.

However the last release of Odamex was on March 29, 2014. There have been many code updates following the release but no new versions due to some plans not being completed. There are currently no “horrible” bugs and repeat offender crashes but the project definitely needs optimizations and maintenance.

If you are interested in helping Odamex, please respond here and/or join #odamex on irc.oftc.net

Projects to consider:
* Implementing Survival Co-op
* Improving BOOM support
* Improving the ACS interpretor
* Implementing UDMF map format
* Improving Heretic and Hexen support
* Heck just pick something and go for it!
