Unrated cut has a bit more human blood but nothing that bad
Green alien blood and small spurt of human blood
Level of violence:8/10.
PG-13 violence type: blood, gore, brutal and graphic.
The majority of the violence is between the Aliens and the Predators. The predators have glowing green blood, and the Aliens have acidic green/yellow blood.
In the extended cut, a lot more human gore is seen, however it has been digitally added and isn't very convincing.
When the Predators arrive on earth, they kill alot of people. All of the deaths are offscreen or cut away right before, and in the extended cut, we can briefly see a knifeblade penetrating a mans body, and blood squirts out. Graphic but brief.
One man is killed, offscreen but we see blood splatters on the snow next to him, not graphic.
One Predator is brutaly killed by an Alien, his tale penetrates the Predator and green stylized blood splatters out. If that wasn't graphic enaugh, the Alien drags the Predator offscreen and green blood splatters all over the place.
One Alien get's his half head cut off. The brain and other stuff in the Aliens head is seen, and some visible blood.
In another extended scene, a Chestbuster (Alien in fase 2) burst out of a womans chest, blood is seen but it's very brief and the camera shake alot.
The Alien Queen is dragged down to the deeps of the Atlantic Ocean. It's tied to a big object. A alien get's it head chopped of after death, the worst part is the sound effect.
Another chestbuster burst out of a dead Predators chest, some green blood, and this scene is about three seconds.
