Insurgency: Sandstorm is the sequel to the standalone Insurgency game developed on the Source engine. The sequel is being developed on the UE4 Engine, delivering high quality graphic, smooth movements, lager maps usable vehicles, new reload mechanics and much more features to come.
As with its predecessor, the game retains various competitive multiplayer modes along with a Player vs AI co-op mode, playable on each side. Of note is that currently, the Security side has access to almost all the Insurgent-exclusive weapons and attachments in Co-op Mode, while the Insurgent side is only able to use certain Security-exclusive weapons and attachments.
The following weapons appear in the video game Insurgency: Sandstorm.
A staple sidearm of the series, the Beretta M9 is oddly available to the Insurgent faction rather than the Security (although it is not inaccurate for the Insurgent faction to have plenty of stolen or secondhand older US military hardware). It costs 2 supply points.
The classic .45 M1911A1 returns as the Insurgents' equivalent to the Security's more modern M1911-based pistols. It has long 1911 trigger with diamond grips and blued finish. It costs 2 supply points and is currently the hardest-hitting Insurgents' pistol.
Colt M45A1
The Colt M45A1 replaces the M45 from the 2014 title, though the M45 MEU(SOC) can be seen in early development footage of Sandstorm. As with the M1911A1, it costs 2 supply points and acts as Security's .45 pistol.
Glock 17
A tan-framed Glock 17 is one of the Security pistols in-game. In the Alpha, the Glock was designated "G17." In the Beta, the weapon was re-indexed as the "M005" likely to avoid legal issues, the name itself likely derived from the USMC M007 designation of the Glock 19M. It appears that that was still not enough to appease the Glock legal team however, and the Glock was removed from the launch version, reworked, and later patched in as the "PF940"; named after a Glock part kit created by a company named Polymer80, the pistol in-game is built off of said parts kit (specifically the V2 model), its the addition of an aftermarket slide with diagonal cocking serrations. It is currently the most expensive Security's pistol costing 3 supply points.
Makarov PM
The Makarov PM is another pistol available to the Insurgents forces. It is the weakest Insurgents' pistol, but also costs 0 supply point.
SIG-Sauer P226R
Also usable by the Security forces is the SIG-Sauer P226R. It appears under its UK Army designation of L106A1. It costs 2 supply points.
Tariq
The Tariq, an Iraqi clone of the Beretta M1951, is another usable sidearm in the game, exclusive to the Security forces. It is the only Security's pistol to cost 1 supply point.
Submachine Guns
Heckler & Koch MP5A2
The March 2019 Content Update added in two variants of the MP5 submachine gun. The Insurgents received the older MP5A2 variant, which features the early "slimline" handguard and "waffle" magazine.
Heckler & Koch MP5A5
The March 2019 Content Update provided Security forces with the MP5A5.
Heckler & Koch MP5SD6
When fitted with a suppressor, the Security's MP5A5 turns into an MP5SD6.
Heckler & Koch MP7A1
A popular community weapon from the previous game, the Heckler & Koch MP7 makes an official appearance in Sandstorm. It is usable by the Security's Breacher class and uses its flush 20-round magazine, with the 40-round extended magazine being available for extra Supply. The base gun costs 4 supply points.
IMI Uzi
The IMI Uzi also makes its official appearance in the game (although in the last game, there is a Steam Workshop mod that replaced the MP40 with the Uzi). A lower-profile, optics friendly charging handle very similar in appearance to the one used on the Uzi in Battlefield Hardline replaces the default Uzi cocking knob. The Uzi is one of the few open-bolt weapons in the game and costs 2 supply points, and is usable only by the Insurgents' Breacher class. By default, the Uzi uses a 25-round magazine, with a longer 32-round magazine and a 50-round drum available via extra supply points.
Assault Rifles
AK-74N
The AK-74N returns from the previous game as the AK-74, although the Warsaw Pact rail makes it an AK-74N. The rifle costs 4 supply points and is usable by the Insurgents' Rifleman, Demolitions, Commander, and Observer classes.
AKMN
The AKMN with a standard fixed stock replaces the folding stock AKMS from the previous game. Like the rest of the AK's, it's modeled with a Warsaw Pact rail, albeit a newer version lifted from the AK-74N model. The rifle is one of the cheapest Insurgents' weapons available, costing 3 supply points. It is usable by the Rifleman, Demolitions, Commander, and Observer classes.
AKS-74UN
The AKS-74U returns as the AKS-74U, and like the other AKs, it has the Warsaw Pact rail making it an AKS-74UN. The rifle is available for the Insurgents' Advisor and Breacher classes, and costs 4 Supply.
Alpha AK
The Alpha AK, a customized AK used by the Russian Spetsnaz Alpha Group and featuring a Zenit RIS handguard and a railed dust cover, is a new Insurgents' weapon in Sandstorm available to the Advisor class which costs 4 supply points. It is fitted with a Tromix extended charging handle, and is stated to be chambered in 7.62x39mm via in-game stats, despite being clearly modeled with a 5.45x39mm magazine.
Enfield L85A2
The L85A2 is available to the Advisor class of the Security faction. By default, it has its original green plastic handguard; the Daniel Defense railed forend is used when mounting a laser or light module or adding a vertical grip. Like the Uzi in the previous game, it was a favorite workshop mod among the community. The SUSAT scope can also be equipped on the L85 as a unique attachment. It costs 4 supply points.
Heckler & Koch G36K
Another popular weapon mod from the previous game, the Heckler & Koch G36K is one of the primary weapons available to the Security forces. The ZF optical sight can be equipped on the G36K. It costs 4 supply points and is available to the Security's Rifleman, Demolitions, Commander, and Observer classes. Notably, the G36K is prominently used during the tutorial map.
HS Produkt VHS
The HS Produkt VHS-D2 appears as a new weapon for the Security faction, available to the Commander, Observer, Rifleman and Demolitions classes. It costs 5 supply points.
M16A2
The M16A2 is a selectable assault rifle, serving as the Insurgents' counterpart to the M16A4; the rifles are nearly identical, save for the M16A2's inability to mount as many types of optics. It costs 3 Supply, and is usable by the Insurgent Rifleman, Demolitions, Commander, and Observer classes. The M16A2 also gains a heat shield handguard when a launcher is mounted.
M16A4
The M16A4 returns from the previous game and is the cheapest rifle available to the Security forces, costing 3 supply points. It is usable by the Security Rifleman, Demolitions, Observer, and Commander classes.
M4A1
The M4A1 makes its return in the sequel. It is one of the most expensive primary weapons available to the Security forces, costing 5 Supply. It is usable by the Security Rifleman, Demolitions, Commander, and Observer classes.
Mk 18 Mod 1
The Mk 18 Mod 1 replaces the Mk 18 Mod 0 from the original game, appearing as the Mk. 18 CQBR. As with the M4A1, it is somewhat higher-cost than basic rifles for the Security forces, though costs 4 supply points. It can only be used by the Security's Breacher and Advisor classes.
Norinco QBZ-03
An interesting choice alongside Security's VHS-2, the Insurgents get access to the Norinco QBZ-03, specifically the 5.56 export version. It costs 5 supply points, making the currently most expensive assault rifle for Insurgent.
Battle Rifles
FN FAL
The FN FAL makes its return in the sequel. It is usable by the Insurgents' Rifleman, Demolitions, Observer, and Commander. It costs 4 supply points and cannot be equipped with a grenade launcher, unlike the other rifles available to the Demolitions class.
FN SCAR-H STD
Available to the Security's Advisor class, the FN SCAR-H makes its official debut in Sandstorm as the Mk. 17 Mod 0. It costs 3 supply points.
Heckler & Koch G3A3
The Heckler & Koch G3A3 officially appears in the game. It is usable by the Security's Rifleman, Demolitions, Observer, and Commander classes, and is the only rifle available to the Demolitions class that cannot equip a grenade launcher. It costs 4 supply points.
Mk 14 Mod 1 Enhanced Battle Rifle
The Mk 14 Mod 1 EBR makes its way back from the previous title. It is available only to the Security's Marksman and Advisor classes. It costs 5 supply points.
Norinco SKS-D
The Norinco SKS-D returns from the previous game. It still has a "paratrooper" barrel, but now it also has its bayonet. Like in the previous game, it uses 20-round magazines although it can use 30 round AK mags with the "extended mags" modification, and the bolt still incorrectly locks open upon firing the last shot despite the lack of bolt hold open on Chinese AK mag SKS models. It is available to the Insurgents' Advisor class and costs 2 supply points.
Machine Guns
M240B
The M240B GPMG was added in the March 2019 Content Update as the second option for the Security's Gunner class, costing 4 supply points. It comes with a 50-round belt in a cloth pouch, but can be upgraded to a 100-round belt in a box magazine with other options of sights, barrel attachments and laser sight.
M249-E2 SAW
The M249 is a primary weapon usable by the Security Gunner class, costing 3 supply points. It comes only with a 200-round belt and can be modified with optics, all barrel attachments and laser sights.
MG3
The MG3 was added to the game during the March 2019 Content Update as another Insurgents' primary weapon for the Gunner class costing 4 supply points. It has a high rate of fire at 1000 rpm, but virtually uncontrollable unless firing with bipod deployed. It comes with a 50-round belt in a drum pouch, but can be upgraded to use 100-round belts in a box magazine, along with optics, suppressor(!) and laser sight.
PKM
The PKM makes its long-awaited arrival to the series in Sandstorm. It is the Insurgents' counterpart to the M240B, usable only by the Gunner class. It costs 3 supply points and comes only with a 100-round belt with options for optics, barrel attachments and laser sight.
Shotguns
Remington 870
The Remington 870 makes its way into the game, replacing the Mossberg 590 from the previous title. It features black furniture with a railed forend and scope rail added to the receiver, with a ghost ring rear sight. Strangely, it utilizes the Rem-Loc stock system found on the 870 MCS variant. This system allows for quick changes of the stock, and comes with its own unique forend, which the game has omitted in place of the police forend. It is usable by the Security Breacher class and costs 2 supply points.
TOZ-194
Also returning from the 2014 Insurgency is the Russian TOZ-194 pump action shotgun. It is almost identical to the Remington 870 in nearly all respects, including its magazine size, rate of fire, damage, and so on. It costs 2 supply points and is available to the Insurgents' Breacher class.
Sniper Rifles/Anti-Materiel Rifles
Remington M24
The Remington M24 makes its way into the game, replacing the old M40A1. It costs 2 supply points and can be used with iron sights or a variety of optics, up to and including a 7x scope. It reloads one bullet at a time and is usable only by the Security's Marksman class.
Mosin Nagant 1891/30
The Mosin Nagant costs 2 supply points and is usable by the Insurgents' Marksman class. By default it is the M91/30 rifle with a straight bolt handle and hex receiver, the correct PU scope and turned down bolt handle are appropriately used when opting to use a scope in a fortunate aversion of the bubba-fied Mosin from the previous game. If there is not a scope mounted, the rifle can be used with stripper clips for faster reloading while empty, at the cost of extra supply points.
Izhmash SVD Dragunov
The Izhmash SVD Dragunov is available to the Insurgents' Marksman and Advisor classes. It can be used with a variety of optics including its unique PSO-1 scope, or even just iron sights.
Barrett M107CQ
The Barrett M107CQ appears in-game as an optional weapon for the Security's Marksman class as the most expensive rifle costing 6 supply points.
Zijiang M99
The Chinese M99 anti-materiel rifle appears as the counterpart to the Barrett M107CQ, given to the Insurgents' Marksman class. Like a few other weapons, the M99 comes with its own special scope, dubbed the "Type 99 scope" in the loadout menu.
Launchers
Carl Gustav M3
The Carl Gustav M3 is the standard reusable launcher for the Security faction, and appears under its US Army designation as M3 MAAWS.
M136 AT4
Another veteran from the previous game, the M136 AT4 is also available to the Security's Demolition class as their single shot launcher of choice.
Panzerfaust 3
The Panzerfaust 3 is available to the Insurgent faction as their analogue of the AT4, being a single-shot launcher oddly enough.
RPG-7
The RPG-7 returns from previous games, as the obvious handheld launcher for the Insurgent faction.
Mounted Weapons
Browning M2HB
The Browning M2HB appears mounted on the Security's technicals as the counterpart of DShK. The unusable low-detail models can be found on vehicles as environmental props in some maps.
DShK heavy machine gun
The DShKM is mounted on the Insurgents' technicals. It has unlimited ammunition and is capable of shredding targets through heavy cover like walls. Oddly enough, it is mounted on Security's AH-64 Apache (AKA "Assassin") as 30mm Cannon.
General Dynamics GAU-19/A
The GAU-19/A is mounted on Security's UH-60 Blackhawk (AKA "Cleric"), which is being used by the door gunners. The gun also ejects spent casings when firing.
