I have got to this guy with only shotgun cartridges. I know you are supposed to shoot the ends of the tentacles, but I can't seem to kill it and am going nuts.

I use the rocket launchers and all my ammo, but to no avail.

Help really would be appreciated.

Nice spoiler in the title, man. There are people on the forums who haven't beaten the game, you know?

fair enough, although it's not like you wouldn't expect a big tentacled monster at some point.

You can't miss with the rocket launchers, and your shotgun cartridges only really work at close range.

But when I fought this guy, I only had a Machine Gun and not a whole lot of ammo so just don't miss with the Rockets and you should PWN him.

OK, the title seems to have changed and therefore I have no idea what the original poster is talking about.
