World of Tanks is a free-to-play, massive multi-player online (MMO) game.
The game allows the player to play on a team of 15 players against another team of 15 players, with the goal of defending your territory, attacking the enemy territory, and destroying as many of the enemy forces as you can while keeping yourself alive. Teamwork and good strategy is the key to the game.
The vehicles in the game are armored vehicles used during the early part of the 20th century, with the oldest Tank having been built in 1917. Some tanks where mass produced while others were only prototypes or “blue print” tanks, which only existed on paper. There are 10 tiers of tanks, which are evenly matched so that the player is on or near the same level as the others on the server.
The tanks are broken up by type and by nation. Each nation in the game (US, UK, France, Germany, USSR, China and Japan) has an array of vehicles that are often unique from the other nations with their own characteristics.
The types are Light Tanks, which are often used for scouting, Mediums, which are support tanks, Heavies, which have high armor and large guns. There are also Tank Destroyers (TDs) which often have weaker armor, but a heavier gun and less mobility. Lastly there is the Self-Propelled Guns (SPGs) which act as artillery. The SPGs are a support vehicle that can launch volleys of shells across the battle field to aid your ally tanks.
