In the tank mission, the controls become unmanageable. Several people have registered the same complaint for at least the last 7 years, and nothing has been done to resolve this issue. I recently requested a refund for this game for this reason, but because I had played for over 2 hours, policy stated I was not eligible for a refund. However, this mission, at least for me, took more than two hours of game play to reach, so by the time I got to this point where the game became unplayable I had already gone past the two-hour mark. So now I have a game I can not play, has no plans to be fixed, and Steam is taking no accountability to refund money. This amounts to deceit and stealing in my opinion. Exceptions must be made and accountability needs to be taken by Steam when they are selling a known flawed product.
