Most violent classic console video games? nothing past 16 bit era

[Richter Belmount]

Sure we can talk all day about pc classic games but that makes this topic to easy. But what about console games where restrictions and censorship got in the way? Im looking for basically games that make you think , how did this get pass censorship or , hey thats pretty gorey and violent for a older game. Stuff like Splatterhouse 2 , Castlevania bloodlines , mutant league football , Clock tower (even though thats a snes import) Violent as in gorey , blood or stuff like realistic ways of killing people that manage to pull that off in the old school era (getting stabbed , strangled)
