Just made an account to figure out a sci-fi horror movie

Hey guys something reminded me of a movie I saw years back when I was a little kid and I need help figuring out what it's called. I can only remember a few scenes but hopefully it'll be enough.

The movie was a sci-fi horror movie I saw in the 90s that had to deal with some kind of killer machines inside a house.  The main characters are a middle-aged white man and a teen (possibly his son).  The first scene I remember deals with them meeting two black women (maybe in the house) who seem to know how to fight.  One of them is instantly beheaded by some sort of flying robotic disc with blades and the other woman ends up teaming with the man and kid.  Eventually towards the end of the movie I guess they find a way out of the house because a car ends up parking out front and the black woman gets in it and asks the man to come along.  For some reason he says no and needs to go back to the house (I guess to maybe finish off the machines), so he ends up returning to the house.  The very end of the film shows the man being overwhelmed and covered with what look like robotic spiders and the son, who is standing at the edge of a pit or something is grabbed from behind by some scary looking man (probably the main villain) and pulled backwards down the pit.

If anyone has any idea what the movie I'm talking about could be, I'd appreciate knowing what it is.  Thanks.

Phantasm III fits your plot points.

Wow I can't believe you knew what it was.  I looked up the trailer and although the movie looks terrible, it's definitely the one haha.  Thanks a lot.
