There is a lot of graphic violence in this movie. Hand-to-hand combat scenes are very rapid, perhaps with deleted panels to speed them up. The combat is more brutal than simply punching scenes, more like UFC combat, with heavy crunching and splat sounds.

A man fights off a horde of zombies from on top of a car. He shoots many zombies and it is seen that blood comes spurting from their bullet wounds and heads. Upon running out of ammo, he then starts to chop at the horde with a machete. This goes on for a few minutes before the horde overwhelms him and drags him off the car screaming. They close over him and smother him with their dozens bloody hands but the camera doesn't show him getting ripped apart, just screaming.

This scene is repeated at several turns. The man then runs out of ammo and another group overwhelms him.
