Strong bloody horror violence

Several zombies are seen thru/o. Most of them bloody. Some of them are seen with their heads off. Sometimes zombies are eating each other. A zombie forces another zombie to eat a bloody zombie. A guy is eating a bloody zombie and then guiltily spits a piece out when he's caught. There's a scene where zombies spit out what looks to be cement.

Fairly tame. A few f-words and some other profanities and phrases.

From when the lady enters the Tower the film is extremely intense. Not for the faint of heart.
