There is a problem, I am not able to shoot the big guy. You may wonder, when you fall away it says "Get off my damn ball" and wont let you shoot until he gets in front on you. The game doesn't give enough time to shoot the brute before he kick you off. You are only able to shoot him when he is just in front of you. You may not get it, but there is a cut scene missing. The cut scene actually shows the brute is getting on to the ball. You may wonder to whom is the character heeling at.
The right solution is to low down the graphics settings, and start the mission. You may see the actual difference. Lowering the grahics basically brings the game intensity to the perfect ratio. You will see the performance difference. You will also finish this mission.
There are many solution availalbe on net. Download this and that; cheats, save games. Well you don't have to download or do anything else, just lower the grahics setting. You can keep the same display resolution.
