Doom: Annihilation is a 2019 science-fiction/action/horror film based on the Doom video game franchise by iD Software. Rather than a direct remake or a sequel to the 2005 feature film adaptation that starred Dwayne Johnson and Karl Urban, Doom: Annihilation is instead a standalone film that was announced to be more closely based on the 2016 Doom video game and its (then upcoming) sequel, Doom: Eternal. Despite this, the game more heavily borrows from 2004's Doom 3 and features numerous references and plot threads adapted from various bits of Doom media, including the games, other iD Software properties, and even borrows a few elements from the past film. Doom: Annihilation is written and directed by Tony Giglio (Chaos).
The following weapons were used in the film Doom: Annihilation:
UAC Space Marine Lt. Joan Dark (Amy Manson) carries a Walther P22 with a laser sight as her sidearm throughout the film. Despite being a .22 caliber weapon in reality, the film portrays it as a strong enough weapon capable of punching large holes in its targets. At different points in the film, Veronica (Katrina Nare) and Dr. Betruger (Dominic Mafham) hold the weapon. A promotional photo shows Rance (Amer Chadha-Patel) holding what appears to be another laser-equipped P22, although he is never clearly seen with one in the film, though it is likely the firearm briefly seen in his hip holster.
Space Marine Winslow (Clayton Adams) carries what appears to be a Beretta M9A1 as his sidearm, evident from the flashlight-holding rail on the frame. While being attacked by zombies, Joan Dark (Amy Manson) takes Winslow's Beretta and dual-wields it with her P22, during which the gun appears to have a two-tone finish, which was evident beforehand, and lightly colored grip panels. The appearance of the former, however, could simply be a result of the scene's lighting. The Beretta also appears to have custom finger rest grooves on the frame above the trigger.
A zombified UAC security officer carries what appears to be a full-sized Glock variant, such as a Glock 17 or Glock 22, in a nylon belt holster. Whatever model it is, it seems to be at least a 3rd generation model, given the visible thumb relief on the frame. Whether or not there are finger grooves on the front strap is difficult to ascertain due to the fast motion of the scene.
Heckler & Koch P30
M4A1 Carbine or AR-15 variants serve as the basis of two of the "space marine rifles." The primary difference between the two is the length of the barrel: Joan Dark (Amy Manson) and Dr. Bennet Stone (Luke Allen-Gale) carries what appears to be a version with a sixteen inch barrel under the housing, while multiple other characters including Captain Savage (James Weber Brown), Chaplain (Louis Mandylor), Pvt. Corbin (Nina Bergman), and Harry (Gavin Brocker) carry a longer, possibly twenty inch barreled rifle. What appear to be suppressors are actually barrel shrouds, as the weapons' A2 flash hiders are visible on the very ends of the shrouds. Otherwise, the futuristic housing on the weapons are virtually the same, containing large, blocky thumbhole (or in this case, "handhole, given the size) stocks with massive "lower receivers" that hold rails with attached flashlights. All of the rifles are further equipped with top two separate picatinny rails on the tops of the rifles, with the rear ones serving as the home for C-MORE Railway red dot sights. All that's visible of the actual rifles underneath the shells are the aforementioned flahs hiders, the stanag mags, the trigger housing, and what appear to be Aero Precision M4E1 upper receivers.
AK-pattern "space rifles"
Space Marines Winslow (Clayton Adams) and Rance (Amer Chadha-Patel) carry full-sized AK-pattern rifles mocked up as more futuristic looking assault rifles. Like the M4 rifles, the actions are visible from underneath the futuristic shells, and both seem to use Tapco AK magazines. The exact variant is impossible to tell. However, despite the sound effects, the rifles seem to be locked to semi-automatic fire, perhaps suggesting a civilian version of an AK-pattern rifle. Li (Jemma Moore) also carries an AK variant, but hers appears to either simply lack a stock or live as a civilian "pistol" variant, with the futuristic housing encasing it having an incredibly short skeleton stock built into it. All three rifles wear an Eotech holographic sight and have angled foregrips that tend to be ignored by their user.
Space Marine Tarek (Arkie Reece) carries a rather strange and awkward looking rifle that's not clearly built on anything that's real. It's not helped by the fact that it's never seen being fired or loaded, and is never seven seen all too clearly in the film just in general, usually appearing in the background or partly off-screen.
12 Gauge Double Barreled Shotgun
Captain Hector Savage (James Weber Brown) brings along an antique-looking 12 Gauge Double Barreled Shotgun with exposed hammers, shortened barrels, sling rings, and a sawed-off stock, a rather obvious nod to the Super Shotgun from the Doom videogames.
Akua's rotary machine gun
Space Marine Akua's (Chidi Ajufo) weapon of choice is a heavily modified RPD in a futuristic housing and with three barrels that, while stationary, feature sound effects to make the audience think that the barrels are spinning and whirring. The only identifiable part of the gun is the RPD magazine and the magazine well. The gun likely stands in for the Doom franchise's chaingun and/or minigun weapons, which also feature rotating barrels, although generally more than three. Interestingly, Doom 3 submachine gun weapon also featured three barrels, with the film itself featuring a variety of subtle, and not so subtle, references to virtually every corner of the Doom series' many entries.
A staple of any Doom related media, Joan Dark (Amy Manson) acquires the infamous BFG9000 near the end of the film and uses it to punish various demonic foes, a far cry from the lack of kills that the "Bio Force Gun" from the 2005 Doom was granted. It does not appear to be built around anything specific, but does feature electronic lighting, a display screen, and has a working magwell for loading the plasma canisters that serve as ammunition.
Along with the BFG9000, Lt. Joan Dark (Amy Manson) acquires a trio of explosive mines from the same storeroom as the BFG9000, which she uses during her escape from the "Dark World."
Although it's not a firearm, no entry into the Doom canon is complete without the appearance of the famous Doom chainsaw, although it's certainly not as tricked out as the one in the previous movie.
