i was thinking that maybe someday, HTC will let us do this.
when ur driving in a tank, you have to go to the turret and lose control of the tank( can't steer it). so maybe when your driving a tank, use some of the keyboard buttons to turn the turret while still have control of the tank.
don't you guys find it annoying to be in a turret and then found out you stopped moving becuase you ran into a tree? sitting duck?
