No nudity.

Several commercials show couples scantily clad or in bikinis or partially under covers having sex. No actual nudity is shown, closest is bare backs and sides of breasts.

Co-ed soldiers shown in showers during decontamination. All nudity is blurred (as if for the documentary).

Tons of blood and gore and zombies being killed and zombies ripping people apart.

Yes, most of it is bleeped out since the movie is shot as if it's a documentary. Some profanity is not bleeped.

Lots of surprise zombie attacks.
