The first project for Kaos Studios (a division of THQ founded by veterans of Trauma Studios, creators of Desert Combat and Battlefield 2 R&D projects), Frontlines: Fuel of War uses the advanced Unreal 3 engine for futuristic, intense fights in an open-world battlefield. In this all-too-bleak future of constant wars over natural resources, two sides compete for global supremacy: the Western Coalition (the United States and the European Union) and the Red Star Alliance (Russian/People's Republic of China). The game's nonlinear single-player campaign has players advancing their side's frontline into enemy territory.
