I ran up and ducked behind like the 3rd crate on the right and RAAM always seemed to get just stand on the opther side of it. Then I would take out the bow, shoot from behind the crate (cover fire), then pull out a machine gun and fire away. When Torque Bow would run out then you just lob grenades. Crate will protect you from the blast 90% of the time.
Rinse and repeat. I used this to beat him on Insane.
Cheap? Yeah I know.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
