Alien movie with a group of fighters called berserkers

A group of cold-blooded killers find themselves trapped on an alien planet to be hunted by extraterrestrial Predators.

In the mid-aughts, Dateline NBC’s To Catch a Predator drew millions of weekly viewers to watch sting operations: men planning to meet minors for sex would instead be confronted by polished host Chris Hansen, then by the police — all on hidden camera.
