There is a lot of violence, however most of it is not graphic.
People are held captive and forced to either harm each other or starve to death.
A man beats a person who is lying on the ground with a blunt object.
2 people are struck with an electrical device (basically a large, homemade cattle prod) and sprayed with gas that renders them unconscious.
A man has a finger lopped off with a blade. He then removes other fingers that were partially sliced. Heavy blood. When the hand (rather, the removed fingers, which are connected) is seen later in the film, it might be considered mildly gory by some, as they are picked up and moved in order to retrieve something.
A man is struck in the neck with a short sword. Heavy blood spray.
A person with a disfigured face is frequently seen.
A man throws a young woman into a wall killing her. It's then implied he bites off and chews on her ear, after licking and sucking blood from her head wound.
A woman is stabbed through both eyes with a pair of open scissors and killed. Other than blood spray and a "flesh-piercing" sound this is entirely offscreen. The dead woman is seen at a later time and the ocular injury is visible. The scissors are removed from her eyes slowly, and with included sound. The camera is focused on the scissor removal. One of the more graphic incidents, and might be considered mildly gory.
A man's face is grazed by a bullet. Minor blood.
A man strikes a woman over the forehead with a blunt object. She is seen bloodied.
A man slams what appears to be a curling iron down a woman's throat, killing her. There is minimal blood, but the camera shows the injury result and might be considered graphic to some.
A man commits suicide via revolver in his mouth. While the camera is slightly fuzzy, blood is visible spraying out the back of the man's head.
A man beats another man to death, striking him in the head several times after he is already down.
A woman is struck by a speeding car.
A man is shot several times at close range.
