The extended, uncensored version has more violence (very little blood).
Numerous people are shot, stabbed, beaten, and blown up at multiple points during the action scenes. Some people are pierced with arrows, others are stabbed with knives, others are shot with guns and rifles. The scenes are moderately violent, but never bloody or gorey (especially in the censored version).
The bad guys are violent, merciless and sadistic, and often attack and kill other people. They also kidnap and mistreat a little girl, who is later slapped by one of them. In one scene, they put up a trap using dead people as marionettes, manipulating them with strings; those people are hung and have their eyes open, it is pretty disturbing to watch.
One man has a harpoon shot through his foot; another is speared through the chest (both scenes are removed from the extended version).
A group of people is about to drown a man in corrosive goo, but he is saved.
During a funeral, a woman's dead body is seen being immersed in a pool full of a corrosive green substance.
A woman is almost raped by a man, but he is stopped. Another man then fights with him and kills him.
A little girl is thrown in the water by a man.
