Well me and a couple other have been playing this game it is pretty cool and what not, has a challenge factor to is as you can not one man it do to the fact that you can bounce shots off armor and small guns can not pentrate thicker armor, and you can hit tanks in there weak spots to do more damage, engine can be knocked out, tracks can be blown off, gun damage, etc. O and there are 10 tiers of tanks. This game is free to play, and you can play pretty far without having to spend money on the game all though you can if you wish.
Some videos of mine just to show the game off.
