I had typed out my response to
@OU Ariakas earlier, and I was sitting there thinking about it more over my coffee.
You start going into horror movies specifically, which Terminator was, and one of the first ones that popped in my head was Kirsty Cotton, specifically in the second film.
If you look at Hellraiser, it's that same sort of character arc that Ripley had dealing with an unknown threat almost beat for beat, just totally different settings.
She's trapped inside a house where she knows something evil is up there consuming things in the attic/ship. Confronts the threat, on the house/ship blows up.
Kristi is then waylaid and called a lunatic because of cenobites/aliens, and then she ends up having to descend into hell/nest. Your firefight moment is the cenobite showdown for hellraiser where you get the audience pumped up, but then ends horribly, but she still comes out on top.
