Profanity regularly used, including 'motherf-ker' twice and 'f-k' used several times. Extended battles between humans and the invaders, with guns, machine guns, and lasers. A police officer is found dead in the woods, hanging upside down and skinned. In a hospital, an alien enters a pregnancy ward, sucks the babies out of the mothers, then implants their own babies inside their wombs. Young children watch their parents get killed by the aliens and the predator parents are torn up, lose limbs, scream in agony as they suffer horrible deaths. While there are the expected scenes of the aliens and predator boring through chests, attacking faces, and impaling any and all victims (with plenty of blood and gore in each attack), that's only the beginning.
The violence is constant and unrelenting.
Predator: Requiem is the 2007 sequel of the franchise.
