World of Tanks is a game that's caught the attention of many MMO gamers thanks to its unusual approach. It's not your standard fantasy or sci-fi game, it's a WWII-themed game that puts you in the driver's seat of a tank. Take your pick: "...your arsenal includes more than 150 armored vehicles from America, Germany, and the Soviet Union, carefully detailed with historical accuracy."
The latest news on World of Tanks is a set of detailed charts on that arsenal. These "development trees" -- one for each of the three countries -- outline the journey from your basic starter tank to the ultimate dream tank.
