World of Tanks (WoT) is a massively multiplayer online game developed by Belarusian company Wargaming, featuring mid-20th century (1930s–1960s) era combat vehicles. It is built upon a freemium business model where the game is free-to-play, but participants also have the option of paying a fee for use of "premium" features. The focus is on player vs. player gameplay with each player controlling an armored vehicle.
World of Tanks has been ported to multiple gaming consoles. The PlayStation 4, Xbox 360 and Xbox One version, called World of Tanks Mercenaries, was developed by studio Wargaming West. World of Tanks has also expanded to mobile platforms under the title World of Tanks Blitz, in addition to a board game titled World of Tanks Rush and a collectible card game titled World of Tanks: Generals. World of Tanks was followed by World of Warplanes and World of Warships.
