The following weapons appear in the video game Serious Sam 4:
Desert Eagle Mark XIX
The Desert Eagle Mark XIX appears as the "SOP38 Pistol". Holds 10 rounds in the magazine and can be dual wielded after learning the necessary skill. It is pretty useful even in the later parts too because the game throws lots of weak trashmobs at Sam at later levels.
Magnum Research (MRI) Desert Eagle Mark XIX, current production model with Picatinny railed barrel and different safety catch - .50 AE
"First they ignore you, then they laugh at you, then you kill them, then you win." - Sam Serious Stone
Mental Gear Solid - Sam sneaks up on two patrolling Octanian Gamma Troopers wielding a Desert Eagle.
Mossberg 590
The Mossberg 590 appears as the "Single Shotgun".
Mossberg 590 with bayonet lug and heat shield - 12 gauge
Double Barrel Shotgun
The Double Barrel Shotgun returns as the "Double Shotgun."
Remington SPR210 Shotgun - 12 gauge
Origin-12
The Fostech Origin-12 appears as the "Autoshotgun". It is classified as a heavy weapon and does not share ammo with the other two shotguns.
Fostech Origin-12 with 9.75" barrel - 12 gauge
Sam wields an Origin-12 - note drum magazine sits higher up and the shotgun lacks its magwell. As the mag gets low on ammo, the shells disappear from it. That is some
Modern Warfare level attention to detail.
M1928AC Thompson
Appears as a skin for the HK416.
Colt M1921AC Thompson with 50-round drum magazine - .45 ACP.
AKM
AKMs are used by Michelle and other French resistance fighters.

Mk 18 Mod 1
A Mk 18 Mod 1 appears in the game as the "M29 Assault Rifle." It uses the same shared asset model from Virtual Warfighter and earlier versions of H3VR.
Mk 18 Mod 1 - 5.56x45mm NATO
Hand Held M134 Minigun
The Hand Held M134 Minigun, a Serious Sam staple, is present, referred to as the "XM214-A Minigun."
Airsoft handheld M134 Minigun with 'Chainsaw grip' to handle the recoil force. This variant was seen in
Terminator 2: Judgement Day. This is an airsoft version which retains the half-circle attachment point for the M60 foregrip from
Predator; the real T2 minigun did not have this - (fake) 7.62x51mm NATO
Name another game that hands you a Minigun with 1500 bullets and unleashes thousands of enemies at you in the opening seconds...
Barrett M107
The Barrett M107 appears as the "RAPTOR 16mm Sniper Rifle".
Barrett M107 Long Range Sniper Rifle - .50 BMG
Dual wielding 2 Barretts because why the hell not? The one on the left is just a mirrored copy of the other one. Part of the ejection port on it should be visible as we can see the start of the mag well. Many other weapons suffer from this when dual wielded.
GP-25
The GP-25 is an unlockable attachment for the Mossberg 590, because it is 2020 and the new Serious Sam game has to have weapon mods, side quests and a skill tree.
Sam pumping the Mossberg gives a good look of the low-detail GP-25 launcher. This shotgun + grenade launcher combo may seem crazy, but it is nothing compared to the black hole greandes or the gun that shoots heat-seeking high explosive chainsaws.
Browning M2 MG
Browning M2s are seen mounted on Humvees.
