You might think that these are odd changes, but it all fits in line with the 10 Rules of Censorship that China requires of studios who plan on porting and releasing games into the mainland. China has strict rules against certain kinds of imagery glorifying or promoting images of death, especially supernatural images such as skulls, ghouls or the undead. These changes have to be applied to a lot of games releasing in the region, whether it's for home consoles or for PC, which is something both Sony and Microsoft had to adopt to when releasing the PS4 and Xbox One within the region.
