The guidelines we had were mostly about bones iirc, especially if they still had some “meat” on them. I don’t remember anything about organs specifically

Actually I remember that one of our unofficial internal guidelines was basically “if resident evil or DMC does it, we should be good”. And both of these feature some gore but are usually very light on stuff like bones, (humanoid) decapitations, etc. Again, I assume stellar blade follows similar guidelines as these games regarding this stuff, because Sony (their publisher) obviously knows CERO pretty well
