Tons of over-the-top action-movie violence, with dozens of faceless guards being shot and killed. A fair amount of blood is shown, especially when one of the good guys is shot in the stomach, and one of the bad guys falls down a flight of stairs and smashes his head. The inmates fight a great deal with lots of punching and pummeling, the guards are shown beating inmates into submission. Some scenes take place in a doctor's office with bloody wounds being stitched up, or needles being injected. A character is tortured with a high powered hose in his mouth. There's also a big explosion.
