This game places you in command of a Tank in WW2. Variously a German, Russian and American in the main game which is set in Europe or German and American in North Africa.
I would have preferred an option to fight as a British commander but you can't have everything.
What you do get is the choice of difficulty levels varying from easy, (Which actually isn't all that easy as the game tightens up as you go) to damned near impossible.
The major weakness in the game, which is only likely to bother real buffs, is the lack of tight control over your subordinate vehicles which detracts from its appeal from a strategic point of view. As an action game however, whee, quite simply, whee!
