Cursed Armour 2? But watch out for the weird scenes of the lady being cut in half then sucking cock and getting fucked, if you think that's weird you still haven't seen anything yet, she transforms with the body of a dog and unspeakable things happen. I think there's even more of the worst scenes, lol
I know that appearance wise the parts are detached, but the in-game premise is that the body is still intact, and the parts are transported somewhere via dimensional magic. (kinda like having a portal at the place where the "cut" is)
The MC even has a scene where she wakes up in the middle of the night and feels her arm being used to jerk someone else at an undisclosed location.
Basically, what I'm trying to say that yes it is a niche fetish, but it's not guro.
From my experience, I associate these RPGM games that explore hardcore themese with mainland Chinese developers:
- Sword Maiden of Azure Dragon (don't know how hardcore the scenes get, but features same ridiculous DRM with online server authorization)
- Evil Goddess
- OverDevil
- Agnietta and the new game from the dev that is in development
- Cursed Armor I, II and the platformer
- probably one or two more that I am missing
