The X-Tended Mod is a large addition to the existing X3:Reunion universe and is the only major mod (as of the 26th May 2010) that has been hosted by the creators of X3:Reunion, Egosoft, on their own servers. (Only 2 mods have been hosted by Egosoft in total.) Many of the ships and ideas from XTM were added to the next game by Egosoft - X3:Terran Conflict. A lot of the XTM team also worked with Egosoft in creating Terran Conflict. This mod massively expands the universe and the game itself, adding over 90 new ships, almost doubling the size of the universe, plus adding many new missions, stations, and things to find.
