****, I ALMOST beat RAAM on insane mode, if found an easy ass way to beat him. I don't know how many more shots I needed on him though, I wasted like 5 clips on him, all open hits too with the locusts away. The stupidass flying things on the side which the helicopter is supposed to shoot down killed me. I was ****en pissed! I'm glad I figured out how to beat RAAM easy!

Yeah, I love doing campaign on Co-op, but ramm is a *****.

Just stick at the end of the train until he gets to you then run to the other side, and keep repeating.

Tip - Use sniper rifle, works wonders.
