Gaijin Entertainment was founded in Russia in 2002 by Anton and Kirill Yudintsev,[4] whose first big project was the PC racing game Adrenaline.

The company now has six offices in total: in Karlsruhe (Germany), Larnaca (Cyprus), Budapest (Hungary), Riga (Latvia), Dubai (UAE) and Yerevan (Armenia).

According to Anton Yudintsev, he was dreaming to enter the Japanese market one day while staying true to their roots as a European company and accept their position of an outsider there.

[48] On 21 June 2020, adult actress Eva Elfie was sponsored by Gaijin's War Thunder, which sparked light controversy within the community.

[49] On 23 September 2022, an official Eva Elfie decal has been added to War Thunder,[50] further strengthening relations between Gaijin and the porn actress.

[51][52][53] High Caliber Mayhem has denied any links to the separatist armed forces and published an explanation claiming that all the money from all advertisements on that channel were spent on humanitarian aid for civilians.

"[51][54] Following an in-game economic change on the 16th of May 2023, a large amount of War Thunder players began revolting against the developers[55] by review bombing the game on multiple platforms, such as Steam and Google.

[60] Steam hid the reviews [61] posted after May 19th and marked them off-topic as the update in question was no longer a part of the game starting from that date.
