World of Tanks is an MMO game based on massive numbers of armored battles. In World of Tanks 30-player teams are fighting PvP battles. The game features more than 150 armored fighting vehicles from pre-WW2 era up to Korean War: light, medium, heavy and super heavy tanks, tank destroyers, self-propelled howitzers and rocket artillery. The game includes German, American and Soviet tanks.
The game offers fast random battles featuring various modes, historic mini-campaigns, tourneys and Clan Wars on a global map, where mighty clans fight for hundreds of provinces employing grand strategy, diplomacy and economic power. Besides individual tank-ace skills, World of Tanks requires team work and a fine balance between light and heavy armor. The game will be available as a free download and is expected to be released in Fall 2010.
