This is an improved version of Warzone 2100, a 3D science fiction real time strategy game developed by Pumpkin Studios and published by Eidos Interactive in 1999. Warzone 2100 offers campaign, tutorial, multi-player and single-player skirmish game modes, unit designer, unit experience system, and everything you would expect from a modern RTS game. The 2.3 Beta4 release is network incompatible with previous versions. (You cannot play multiplayer games with previous versions of Warzone.) Skirmish savegames from past games do NOT work on this release. This requires physfs, quesoglc, and OpenAL.
