The S12 (Saiga-12[1]) is a weapon appearing as a semi-automatic shotgun in Call of Duty: Black Ops II and Call of Duty Online, and as a fully-automatic shotgun in Call of Duty: Modern Warfare Remastered.

Call of Duty: Black Ops II

"Semi-automatic shotgun. Deadly at short range."
— Description.


The S12 is the standard shotgun of the Mercs and the ISI. It is one of the earliest unlocks for customized loadout and is available after completing "Pyrrhic Victory". However, it is never part of any recommended loadout (most likely because it's never used by friendly factions). The weapon is semi-automatic and sports a 10-round magazine (14 with Extended Clip), moderate damage, range, firecap, recoil and hip fire spread, making it sufficiently consistent with one-hit kills in close quarters. Although, outside of close quarters, the high rate of fire is enough to offset the lower one-hit-kill range than other shotguns.


The S12 is unlocked as soon as Create-A-Class is unlocked at level 4, however, unlike the Remington 870 MCS, it must be bought with an unlock token. The S12 has a 10 round magazine, a reasonably high firecap (much higher that other semi-automatic shotguns in the previous games), mediocre hip accuracy and a low-moderate range. These combine to cause the S12 to burn through ammo quickly if attachments are not used to their full potential, and since the S12 has a relatively long reload time, this will leave the player vulnerable as reloads are common or slow without Extended Clip or Fast Mag respectively. The near-identical applications of both magazine modifications means that both are somewhat equally useful. On a smaller map, Extended Clip may be more useful due to the possibility of providing prolonged firing, whereas on a larger map, the necessity to do this is reduced, resulting in Fast Mag being a better choice, especially when add time during reloads with it will be almost instant. When using the S12, due to its lower-than-average firecap, it is advised that players do not oversample the trigger, as it will result in slower firing. Instead, it is recommended that players wait a short while between shots for maximum output.

Another attachment that hugely benefits the S12 is the Long Barrel attachment. This attachment dramatically increases the S12's killing potential at ranges unusual for a semi-automatic shotgun, and so it excels in conserving ammunition and keeping reloads to a minimum, as well as providing incredible power at ranges that the S12 would otherwise perform poorly at. The usage of a sight on the S12 is rather redundant considering most kills will probably be attempted from the hip on account of the S12 being a shotgun, and also because the iron sights on the S12 are clear and open, more than is sufficient for the close-range encounters the S12 would ideally be used in. Out of all the shotguns, the S12 is arguably the best one for a "crowd control" role, as it is the only shotgun that can be fired without interruption — the other shotguns must either be pumped (Remington 870 MCS, KSG) or have its chamber cycled (M1216).

Conclusively, the S12 is a spamming shotgun that accompanies well with rushing in objective games such as Domination or Hardpoint, where the high firecap can greatly help with room-clearing or attacking flags. Players are strongly recomended to keep a secondary as the S12 is useless at range.



"Hmm...very much in the lieu of the Russian classics. I can see why Misty appreciates its reliability."
Marlton Johnson, when obtaining the S12 from the Mystery Box.

The S12 appears in all Zombies maps (with the exception of Origins) , available out of the Mystery Box for 950 points. By default, it has the same high damage with 10 rounds and 30 reserved ammo as from multiplayer. It is not a very effective shotgun, taking numerous shots to take down one zombie as early as round 10. Having only 40 rounds, a slow magazine reload speed, and decent automatic fire makes this a sub-par weapon. 

When Pack-a-Punched, it becomes the Synthetic Dozen. This increases the guns reserve ammo to 50 rounds and increases damage. Pack-a-Punching the Synthetic Dozen a second time adds a random attachment, such as Fast Mag or Reflex Sight. Ammunition is still a big concern with this weapon, and the damage doesn't support the low starting amount of ammunition, either. Players must usually rely on a Max Ammo to replenish the S12's ammo supply, and due to the fact that ammunition can't be purchased off the wall, makes the S12 hard pressed for ammunition.

Call of Duty Online

The S12 appears in Call of Duty Online as the GPAS-12.



Call of Duty: Modern Warfare Remastered

The S12 returned as the Kamchatka-12 in Call of Duty: Modern Warfare Remastered via an update on February 7th, 2017. It is fully-automatic rather than semi-automatic.

The Kamchatka-12 can kill in one hit within its effective range, firing eight pellets similarly to most of the other shotguns. However, the range is very short, and damage per pellet is less than that of any other shotgun. This results in the Kamchatka-12 being less likely to kill in one shot than any other shotgun. It makes up for this, however, with being fully automatic and having a relatively generous 8-shell magazine. The 468 RPM is slower than the theoretical maximum the Rangers could accomplish, and is a good deal slower than the rate of fire of other fully automatic weapons, but it is still rapid for a shotgun and in most cases more than enough to kill opponents within effective range before they can react.

The Kamchatka-12 has great uses on maps such Shipment, being able to take out targets with much ease due to its high rate of fire. However the high rate of fire can sometimes leave the player stripped of ammunition, which can be alleviated with the perks Bandolier and Sleight of Hand. Sleight of Hand is particularly beneficial: The Kamchatka-12 has a moderately slow reload time of 2 seconds, and reload cancelling has a minimal effect.

As the weapon is fully-automatic, bots will fire the gun without stopping untill they are out of ammo or the target is dead.

  • In the alpha and beta stages, the S12 had a small skull on the charging handle.
  • "Made in Russia by Izhmash" can be seen stamped on the left of its receiver.
  • Interestingly, there's a small heart on the iron sights, on the lower right. This can be easier seen while aiming down the sights.
    • There is also a visible Fleur-de-Lis symbol near the iron sights. This is seen when holding the gun by the hip (not aiming down the sights).
  • The serial number for the S12 is 27395872.
