The opening credits contain some nudity, looks like both male and female. He is playing a video game where their avatars are wearing clothes to cover up their private parts.

Intense and frequent zombie action/violence throughout. Characters are attacked and killed by guns, golf clubs and bladed weapons.

A firefighter zombie's hand is cut off with a hatchet. Bloody and probably the most gory scene

Some profanities are used but not very much.

F words are used 3-5 times that's it

Not sure if there was much the movie is in Korean.

Some alcohol drinking is present.

In one scene a policewoman tries killing zombies with a revolver but is quickly killed and bitten as she runs out of ammo. Four zombies are seen biting on her and this may be frightening to some viewers.

This film may be emotional to some users, including towards the end.

A woman asks a man to shot her. They are both crying but choppers can be seen flying, the man notices, and he doesn't shoot her. While they look at the window the woman says "What the f*ck is going on?"
