Starsiege
Starsiege is a mecha-style vehicle simulation game developed by Dynamix and released in 1999. Starsiege is set in the Metaltech/Earthsiege universe, which contains its predecessors Earthsiege (1994), Battledrome (1994), and Earthsiege 2 (1996). This universe also includes action game Hunter Hunted (1996), strategy games Mission Force: Cyberstorm (1996) and Cyberstorm 2: Corporate Wars (1998). It also includes the sequels Starsiege: Tribes (actually released before Starsiege) and all subsequent Tribes titles. In 2015, this game and the rest of the Metaltech/Tribes series were released as freeware by Hi-Rez Studios, but Battledrome and the Cyberstorm series were not.
