This game i can't remember

There's probably a board somewhere for these threads but i couldn't find one.
 
 So i was watching a Daikatana LP because the late 90's FPSes fascinate me when i suddenly remembered this game i saw once.

I don't remember any names. All i remember was that it was a FPS, and I'm pretty positive it was on the PC, but i think it might have also been on the Xbox. What really sticks out in my mind about it was that there was an episode of cheat where they showed all these locations of these buck toothed fish, and if you found them all two fish with Gatlin guns helped against the final boss.

So...any ideas? Pretty sure you fuck the female lead in a pond but that might've been another game.

Yeah, the "Can't remember the name of this game" thread is pretty active with people trying to identify games that others have forgotten. Your fuzzy memories would probably be best applied in that thread.
 
For the sake of reducing redundancy, I'm going to close this thread down.
