Regular talk about one of the characters being a virgin. No sex or nudity.

War theme so shooting and explosions throughout. Lots of (fake looking) blood. Some mutilation.

A legless corpse can be seen.

Quite mild for a zombie/war movie, there's no gore and there are no gory gut munch scenes like you see in most zombie movies.

Most zombies get shot in the head, the only thing you see is a red cloud when one of them gets shot. So no squirting blood or whatever.

Sweating throughout (at least in the English dub).

Smoking and alcohol drinking. Not a main feature.

More action rather than peril overall. One of the tamer zombie films.
