This mod (actually a modmodmod) of RFC Epic/Marathon features the Koreans (from Warlords) as new and playable civilization, and accomplishes this without the removal of any of the other civilizations in the game.
The Koreans can be played in both the 3000 BC and the 600 AD scenario.
To play: download the RAR file, and unzip it into your Beyond the Swords\Mods folder. Then start it by selecting "Play a Mod" from the main menu of BtS.
For a complete list of the features and updates see THIS thread, where your feedback will be appreciated.
