Resident evil 4

[Kaori]

I downloaded this game off PSN and this is one horror game that doesn't disappoint, so anyway the setting is in a rural town in spain where the people are infected with parasites that turn them into homicidal maniac's and you're supposed to find the U.S president's daughter all the way there.
Anyway I just wanted to ask for help, I'm stuck in the castle having to find Ashley while fending off nutjob's on a bridge, and one of them has a rocket launcher.

Just throw the harpoon at it, after the battle in the next chapter get back on the boat and harpoon the fish, you can sell them to the merchant who is in a nearby cave on the lake.

oh, it was harpoon, and i know how to defeat it, i saw a friend doing it, i just swim around and wait for it to swim to me, then swim back into the boat and harpoon it, with that i killed it, it was more interesting >_<, also, i stopped playing it cuz my ps2 is damaged
