Operate your tank through the steep mountains to the enemy base! Some ally plains will fly by, but they won't help you. Enemy planes will surround you in no time, but somehow you'll have to find a way to reach the goal. Use low gear to climb up the hills, and high gear for going down the hills. The enemy planes will drop bombs aimed for you, so fight back using your canon! Using the canon will slow you down, so be carefull!
