The Korax Mod page on ModDB was originally set up not so much by us the developers but by some of our fans, and until a short time ago we had no control over its contents. Not only did it contain some incorrect information, the only downloads were a broken and abandoned beta and a "demo" (actually first beta) of one of our different projects.
The last stable version of KMOD is v2.8 from 2004, which has now been uploaded here. There has been no meaningful development on this mod since then. The successor to KMOD is KoraxRPG, an FPS-RPG engine, the first game based upon it is Scattered Evil (also here on ModDB).
