Police Story 2
Tiger Cage 2
Guyver 2
That Tiger Cage 2 fight is an all-timer for sure, and the steam in an industrial setting at night is such an 80's thing, from music videos to movies. I was just watching a movie that's like Jaws but with a wild hog in the Outback, called Razorback (from the director of Highlander) that looks much the same.
There's so many good choices, but I have a few that came to mind right away.
"Yes, we got all the martial arts. Yes, even Mystery Raven. Shit, I called him *first*."
Jet Li, you will always be famous.

Such a nasty little fight in an enclosed space.

Stretching the definition to "gunfight scene", and it's a bit longer, but I love the buildup, the music especially, and Sharon Stone looks about as cool as anyone ever has drawing that smoke wagon. Russel Crowe too, him and Gene Hackman are unreal in this movie.
Okay okay I'm gonna stop there, turns out I have more than a few.
