War Thunder is a free-to-play military vehicle combat game developed by Gaijin Entertainment. It features combined arms warfare across air, ground, and naval battles, with a massive roster of historically accurate vehicles spanning World War I through the Cold War era and beyond.
Players progress through national tech trees representing major powers — the USA, Germany, USSR, Britain, Japan, China, Italy, France, Sweden, and Israel — researching and unlocking hundreds of aircraft, tanks, warships, and helicopters. Battles can be played in arcade, realistic, or simulator modes, each offering a different level of authenticity and difficulty.
The game is known for its detailed damage modeling, realistic ballistics, and regular updates that add new vehicles and events. A large and active player base drives a competitive meta, while premium vehicles and account progression are among the most traded items on secondary marketplaces.
