World of Tanks is a MMO developed by company called Wargaming, featuring early to mid-20th century era fighting 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, which may be a light, medium or heavy tank, tank destroyer, or artillery. World of Tanks Console Edition is currently out for both xbox 360 and xbox one with full cross-play with one another. World of Tanks is also released for PS4 on public beta as of Nov. 28, 2015.
