War Thunder is a cross platform vehicular combat MMO developed by Gaijin Entertainment for Microsoft Windows, OS X, Linux, PlayStation 4, and Shield Android TV. It will soon be released for Xbox One. The game is based around combined arms battles on air, land, and sea with vehicles from the Spanish Civil War to the Cold War period with an emphasis on World War II. Players have access to more than 800 playable aircraft, tanks, and ships from the Soviet Union, Germany, the United Kingdom, the Japanese Empire, the United States, Italy, France, and China (only on the Chinese server). Other nations, such as Canada, Australia, and Romania, are also featured as part of the arsenal of the six main nations. Most in-game maps are either directly or indirectly based on real battles of the era such as in Stalingrad, Russia, or Peleliu, an island in the Palau chain, though there are exceptions, such as a speculative German invasion of Britain inspired by Operation Sea Lion.
