Warzone 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.

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.

Why is Warzone running so slowly?
First make sure your system is set up correctly for OpenGL games. That means especially to use the most recent drivers for your graphics card (though if you already have those, sometimes those have new bugs, and downgrading to an older version might work), and on Linux perhaps the non-free binary drivers instead of the open-source ones. Make sure you get the newest drivers from the website of your graphics chip's maker (usually AMD, Nvidia or Intel), those from Windows Update might have worse OpenGL support.
