World of Tanks (WoT) is a massively multiplayer online game developed by Belarusian company Wargaming, featuring 20th century (1910s–1970s) 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, from the time of Pre-World War 2, to the Cold War-era.
World of Tanks has been ported to multiple gaming consoles. The PlayStation 4, Xbox 360 and Xbox One version, called World of Tanks: Modern Armor (formerly World of Tanks: Valor), 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.
