How do you kill raam in gears of war 1

First you need the Torque Bow (with full ammo) and the Lancer (full ammo). Straight away, go to the furthest block on the right. When the bat things move away, hit Raam with the Torque Bow, preferably in the face. Do this a few times. But in between each shot with the Torque Bow, shoot some rounds of the lancer into his face. Do this a few times and he should die.

THE MOST IMPORTANT THING IS... STAY IN THE LIGHT!!! The bat things will kill you instantly. If this doesn't work first time, keep trying and hope to god you kill him! this is crazy but GO BEFORE THE LIGHTS GO OUT THERE IS A MACHINE GUN U DIE EASY but it works
