The idea of the game, according to the developers, arose on December 29 or 30, 2008, although the decision to make a game about tanks came after a conversation in Moscow on December 12, 2008, where they thought about what to make a game about. Prior to that, the developers were working on a fantasy-style game. In the spring of 2009, game designer Sergey Burkatovsky, also known as SerB, joined the company. Soon the project was given the code name "Tankodrom". Work on the first version went on until the summer of 2009. Then the closed alpha test of the game began.

Alpha testing of the game began in September of that year; at that time, only five tank models and one unfinished map were created. By the time of the closed beta testing on January 30, 2010, several dozen models of armored vehicles and three fully finished maps were already ready. For five months, about 40,000 applications were submitted for participation in the beta test, and more than 400,000 battles were fought during testing. In March 2010, the developers announced that they intend to develop the project for at least another 5-7 years.
