If you are up on the top of the structure, keep shooting him in legs until he falls, then shoot him in his melon, thats the head, run alittle, turn around and repeat the process until he croaks. I played that level a bunch of times til I got it right. Hope this helps you out. GOOD LUCK
I've played resident evil 1,2,3, and am almost finished with 4. Nothing is cooler than turning off the lights and getting submerged in these games!
