gore

There are a lot of bullet hits and as Dorian here said there's lots and lots of blood. Riddick slits some throats open, breaks necks and brutally beats people to death. Also, didn't the dwellers fall to pieces when shot? So i'd say there is a lot of violence but not that much of human intestins. Just about as much blood and gore as you can have without it being too "Riddickulous". Heh, heh.
