Vamptech

I’m looking to make a mad engineer who’s obsessed with blood. I know there’s a bunch of jumps with perks centred around making blood or controlling blood as a superpower, but what jumps have perks/items centred around making machines that utilize or are fueled by blood. So far, the only ones I’m aware of are bloodborne with its trick weapons and I think Ultrakill… though I might need to double check.

Side note: please don’t include nanotechnology that are embedded into bloodstreams. That’s not the kind of tech I have in mind.
