World of Tanks

Recommended this by a friend at work.. basically, world of tanks is a free to play MMO but is currently in Beta testing (which I managed to get involved with)

Basically, the premise of world of tanks is to take your tank onto the battlefield and either destroy all the enemy players, or capture their base.. at the moment the only game mode is standard 15 v 15 battle (destroy or capture) and currently there are numerous tanks you can choose from, and in the full game there will be over 150 tanks to choose..

Each battle you gain experience points, that you can use to research upgrades to your tank (bigger gun, better engine, suspension etc) and your crew also level up in terms of how well they do their jobs..

World of tanks will be available to all by end of the year.. Have a look!
