and- tapping the cybernetic vampire vein even earlier- the Kris Kristofferson masterpiece that is Knights.  (I had trouble watching THAT while getting drunk.)
		
		
	 
Robo-Vampire predates that, coming out a year(?) After Robocop.
Looking it up your Knights movie sounds like it has a comprehensible  (if stupid) plot.
RV?  Not so much.  
Set in an '80s jungle, there's DEA style drug agents, necromancers, Chinese hopping vampires (one of wich wears a rubber gorilla mask), a scantily clad female ghost - who for no reason rips her top off late in the movie, flashbacks to an irrelivabt love stoey, the Robo hero is dressed in silver painted padded armor, TERRIBLE  effects/sound/stunts, inexplicable actions & diologue, and then it ends.
They took several bad movies, mashed them together, & filled in some bits.
I have this on a compilation disc (of other bad sci-fi).  The 1st time I saw it I was dead tired & fell asleep about 20m in.  It made no sense.  I woke up in time to catch the last 15m.  It made no sense.
"Ok", I thought, "I did sleep though the middle parts...."
So I watched it all the way through the next night.
It STILL made no @$&* sense!  I just saw more of it.
So I shared it with my D&D group.
We now use it as a hazing ritual when new people join our game.  If you can sit through this & then give an explanation of what was going on?  Your character gets to start at equel lv/power as the rest of us. 
That's how bad RV is.  God's of Egypt won't come close to it.
