PlanetStarsiege has released the Xtreme map pack for Starsiege: TRIBES, a collection of maps originally planned for the Starsiege: TRIBES Extreme version that will be in stores this fall. These were not, however, made internally by Dynamix: they were created by an independent group. There are also a few screenshots available that show off the impressive architechture in the maps. Likewise, those can be found at PS.
