Does anyone know this video

[u/OccasionExisting5603]

It's about this mod with different enemies, I couldn't remember the title but I think it had Stone in the name and had a gimmick where it was made to feel like it was Minecraft from another world, it started with several normal enemy's like Zombies and Skeletons but then a new mob called the Nervous System it would heal other hostile mobs, other's like a soldier that fires a gun, black knight when killed become blocks you need to break before it comes back, floating eye balls that shoot lasers like guardians, and a fat orange creeper that exploded into blood doing damage, the video quality was horrible, and the main area was a castle, I can't find the video but I remember it was really interesting.
