The following weapons appear in the film Predators:
Predators is the 2010 sequel to the films Predator and Predator 2. Produced by Robert Rodriguez, it stars Adrien Brody as Royce, a mercenary captured and sent to a Predator homeworld along with seven other 'human' predators.
Royce (Adrien Brody), the leader of the humans carries an AA-12 automatic 12 Gauge shotgun throughout the movie, it is fitted with a drum magazine loaded with Frag-12 rounds, accompanied by a Surefire M900 weaponlight foregrip, and custom camo paint that appears to be similar to the US Army's pixelized UCP pattern. It also could be more closely related to the current USMC MARPAT woodland pattern.
M134 Hand held Minigun
Nikolai (Oleg Taktarov), a member of the Spetsnaz Alpha Group carries a hand-held M134 Minigun substituting for a GShG 7.62mm machinegun thats described in the script, reminiscent of the gun used by Jesse Ventura in the original film. When Nikolai first uses the Minigun a stoppage occurs. Nikolai is forced to fix the jam and reload the weapon. Nikolai later uses the Minigun to slay two Predator hounds and to lay down suppressing fire on Predators before the gun is destroyed in battle by a well aimed shot from a Predator Plasmacaster. A lot of the firing scenes were shot with a prop weapon with a CG muzzle flash added. When the weapon is first introduced a real gun is used for some closeups while Nikolai is firing it.
Blaser R93 LRS2
Isabelle (Alice Braga), an IDF sniper, carries a Blaser R93 Sniper Rifle fitted with an Elcan DigitalHunter scope (substituting for the Heckler & Koch PSG1 described in the script). In several scenes, we hear the scope adjusting even though she isn't hitting any of the buttons. Isabelle uses this weapon to take down Predator hounds and uses it to wound a Predator near the film's finale. She also attempts to take down another hunted alien but after what appears to be a great shot at a fast moving target, she notes that she actually missed.
AKMS
Mombasa (Mahershalalhashbaz Ali) , a member of an RUF death squad, carries an AKMS rifle with the stock folded up throughout the movie, he once uses it to save Stans from an attacking Predator Hound when they first encounter them.
The main sidearm of Isabelle (Alice Braga). She draws it to face a Predator Hound after her rifle runs dry. She fires a couple of rounds at an approaching hound to no avail then prepares to kill herself with it for a painless death before the Predator Hound can get her, only to be saved at the last minute when the Predators call the Hounds back.
Custom Beretta 92FS Inox
A custom Beretta 92FS Inox with custom grips and a compensator is carried by Hanzo (Louis Changchien), a Yakuza assassin who uses it until he acquires a katana from Noland's weapon cache.
M1911A1
When the group finds the dead American he is grasping an empty M1911A1 with the slide locked back indicating that it is out of ammunition.
Tokarev TT-33
After his Minigun is destroyed by one of the Predators, Nikolai (Oleg Taktarov) is seen using a Tokarev TT-33 he was carrying. He fires it at a Predator in Noland's hideout when he goes back to save Edwin.
Mk 2 hand grenade
Several Mk 2 hand grenades are seen among the weapons in Noland's (Laurence Fishburne) arsenal. Royce (Adrien Brody) later strings several of them together in a trap for the 'Berserker' Predator.
M18A1 Claymore
When Nikolai (Oleg Taktarov) sees Noland's weapons cache, he eyes a M18A1 Claymore anti-personnel mine on the table. Nikolai apparently grabbed the Claymore mine offscreen, because he is seen using it prominently later.
Noland's weapons cache
When the group are taken to Noland's cave, they see he's collected a mixture of weapons, some human and some alien; most noteably a Phase Plasma rifle in 40 watt range. There's also a grenade launcher of some sort, used to fire a flare.
