There are nude magazine pictures on the wall in the background that are very noticeable.

Nothing.

Moderate amounts of fairly nasty and bloody gore including an exploding head, a leg getting bitten off, some melting body parts, and various mutant creatures getting messily shot up.

Infrequent but somewhat strong, including 2 or 3 uses of the s-word and the f-word, as well as multiple uses of "son of a bitch."

Nothing.

The multiple nasty gore scenes and bizzare monsters may disturb some viewers.
