Also, scenes without torture also have bloody parts, including gunshots.
In the opening sequence of the film we see a man strapped to a table of some sort, we see the hands of a killer preparing bandages which he puts around the bodies face, while this is happening their is acid dripping into a beaker, the victim wakes up when the cast is set around his face and has two tubes going up his nose. The tubes lead to a funnel which the acid is poured into, causing the victim to violently thrash while blood pours out of other tubes.
In one of the traps Jennifer has a shotgun pointing at her head, and another shotgun next to her pointing at her dog which is in a metal basket, a 30 second timer starts and if Jennifer does not shoot the dog she will be shot herself. at the last second she shoots it, there is a lot of blood and chunks stuck to the cage but there's no body left over, it just pretty much explodes.
At one point one of the characters has a tooth ripped out of his mouth which is made to look quite graphic. lots of blood and holes from gunshots which are mostly in the end scenes.
