Warzone 2100 is a 3D real-time strategy game, developed by Pumpkin Studios (Archived website) and published by Eidos-Interactive. In late 2004 Warzone was released by its copyright holders, Eidos-Interactive, to the public under the GNU General Public License and the Warzone 2100 Resurrection Project was born.

In Warzone 2100, you command the forces of "The Project" in a battle to rebuild the world after mankind has almost been destroyed by nuclear missiles. The game offers campaign, multi-player and single-player skirmish modes. An extensive tech tree with  over 400 different technologies, combined with the unit design system, allows for a wide variety of possible units and tactics. 

Although comparable to Earth2150 in many significant aspects, it does contain some features that are unique. These include various radar technologies, a greater focus on artillery and counter-battery technologies, more frequent in-game cinematic updates as gameplay progress, as well as a different vehicle design method.
