KSG 12

The KSG 12 is a bullpup pump-action shotgun featured in Call of Duty: Modern Warfare 3 and Call of Duty: Black Ops II and in Call of Duty: Zombies.

Multiplayer
The KSG 12 is unlocked at Level 4 in multiplayer. The KSG is a high capacity bullpup pump action shotgun dealing high damage. It features the second-highest damage per pellet of any manual-action shotgun (the others being the SPAS-12 and Model 1887), but firing slightly slower than the aforementioned weapons at 60 RPM. This is balanced by the shotgun's unparalleled capacity, tied with Striker at a 12 shell capacity. In addition, the damage at the edge of the KSG's range is moderate, even allowing for one-shot kills at the edge of its range, but kills at this range are unlikely due to the slow pump action and high spread. When fired from close ranges, the KSG is more likely to score a one-shot kill than any other shotgun. This shotgun is excellent at conserving ammunition, as its extensive amount of starting ammunition means that not only is reloading not an issue, but neither is the threat of running out of ammunition, even when fired over zealously.

On the January 25th (February 3rd for PS3) update, the USAS 12 and KSG 12 shotguns were buffed to increase effectiveness. The KSG 12 now shoots 9 pellets by default, as opposed to 6 previously. This essentially gives the KSG a 50% damage increase. This makes it function similar to how it did when used with the Extended Magazines attachment prior to the patch.

Interestingly, the grip attachment will increase the reload time on the KSG, and will add a second shell ejection sound effect when firing the gun while aiming.

Survival Mode
The KSG 12 is available in Survival Mode at level 26 and costs $2000. Its slow rate of fire makes it difficult to engage multiple targets, but the damage of the KSG means it will usually take out an enemy in two to three shells. A unique feature about this weapon in Survival Mode is that it stuns the enemies for about one second, as opposed to the other shotguns that stuns the enemy for about 0.5 second.

Call of Duty: Black Ops II
"Pump action slug shotgun. Fires a single slug for high damage at longer ranges."

- Description

The KSG 12 returns in Call of Duty: Black Ops II as the KSG.

Campaign
This shotgun appears in the mission "Karma" in a security weapons cache. After completing the mission "Odysseus" the player can select it for use anytime before a mission. In the campaign, it fires buckshot, unlike its multiplayer counterpart, which fires slugs.

Multiplayer
The KSG is unlocked at Level 34. It is the third shotgun available to unlock. It is the only shotgun in the game to fire slugs instead of standard buckshot ammunition that is fired by other shotguns. As a result, its one-hit-kill range is superior to all the other shotguns, killing in one to two shots at medium range. However, since it only fires a single slug, it is considerably harder to land shots on targets compared to other shotguns. It is recommended to aim down the sights instead of hip-firing. It  is also strongly recommended not to crouch or prone then shoot immediately as the shot will be inaccurate. At the edge of its effective range, the KSG will kill in one shot if it is a headshot, so it is possible to "snipe" enemies at a surprising distance.

The Long Barrel is an excellent attachment for this weapon as it increases the KSG's effective range even further, increasing effectiveness at medium range. The Laser Sight is also useful, as the higher accuracy from the hip can prove useful if the player is unable to aim in a tight situation. The Adjustable Stock can be an effective choice, as aiming down the sights with this weapon is generally more effective than hip-firing, but because the Stock only boosts movement speed while ADS for shotguns by 8%, the benefit is minimal. The Suppressor on this weapon slightly lowers its range and one-hit-kill ability, but still is capable of executing silent kills at decent ranges. Firing shortly after switching stances greatly decreases accuracy with the KSG. The use of Fast Mag permits two shotgun shells to be inserted simultaneously, effectively halving its reload time, although this usually is not needed since the KSG has a magazine capacity of fourteen rounds and a low fire rate. The Millimeter Scanner can be used to great effect on maps with lots of thin cover, due to its unusually high penetration (compared to the buckshot shotguns) and high damage per slug.

The KSG is the fourth weapon tier in Gun Game, where it is equipped with the Quickdraw Handle attachment.

 * Adjustable Stock (unlocked weapon level 6)
 * Suppressor (unlocked weapon level 7)
 * Extended Clip (unlocked weapon level 8)
 * Quickdraw Handle (unlocked weapon level 9)

Zombies
In Origins, the KSG is available for purchase through the mystery box for 950 points. It sports very high damage that can be effective in the later rounds if aiming for the head. When Pack-a-punched, it becomes the Mist Maker, resulting in a larger magazine, and higher damage, infact, its damage is so high that it is a one hit kill till around round 30-32(Including headshots), with double tap, without it its effective until round 30. Making it the highest damage shotgun in zombies that isnt a wonder weapon.
