Chain shotgun

"A magazine-fed fully automatic shotgun. It is even shorter-ranged than a typical shotgun, but is extraordinarily dangerous due to burst fire."

The chain shotgun is a very short range, multi-shot weapon which fires 3-shot bursts which deal fairly high damage individually (X3); a slightly shorter delay between each shot; a moderate time between bursts; slightly lower overall accuracy and slightly heavier weight.

Acquisition[edit]

Chain shotguns can be crafted at a machining table once the gas operation research project has been completed. Each requires Steel 70 Steel, Component 5 Components, 31,000 ticks (8.61 mins) of work modified by the general labor speed of the crafter, and a crafting skill of 6.

Chain shotguns can be purchased from outlander and orbital combat suppliers, outlander faction bases, or obtained from the following raider kinds:

Raider Kind Chance Average Quality Health
Mercenary gunner 12.36% Normal 70-320%
Ancient soldier 11.05% Normal 100%

Analysis[edit]

In terms of pure single-target DPS, the chain shotgun is the strongest firearm in the game and beat only by minigun against massed targets. This is counterbalanced by the shortest range of all human usable ranged weapons, equal to that of grenades.

It fires a 3-shot burst, with each round as strong as a pump shotgun, but with significantly higher fire rate. Raw damage output is amazing, only being surpassed by the minigun (before accuracy) and the single-use triple rocket launcher. In addition, the chain shotgun can stagger pawns as large as a centipede. The only enemies that cannot be staggered by the chain shotgun are the Elephant, Megasloth, Thrumbo, Devourer Content added by the Anomaly DLC, Centurion Content added by the Biotech DLC, Diabolus Content added by the Biotech DLC, Tunneler Content added by the Biotech DLC, War queen Content added by the Biotech DLC by virtue of body size as well as the hussarContent added by the Biotech DLC, revenantContent added by the Anomaly DLC and chimeraContent added by the Anomaly DLC when raging, by virtue of stagger immunity.

While each burst is not particularly accurate, stray shots can occasionally hit surrounding targets, making it a good crowd-control weapon. The minigun has clear superiority for crowd control, but is much more expensive and has unique downsides such as terrible accuracy, a massive warmup/cooldown cycle, and a reduction in wielder move speed.

The chain shotgun is best suited as a close-quarters offensive weapon, though is an excellent supporting weapon due to its stopping power. It can be used behind melee fighters, and specialized killboxes take advantage of the shotgun's strength. It is especially good against infestations and drop pods due to its stopping power, damage output, and crowd control, combined with the lack of range constraint. Note that even a shotgun won't be fired in melee combat, so keep your shotgun-wielding pawns out of melee, make good use of melee blockers, and engage chain shotgun-wielding enemies in melee.

Stats[edit]

Against an unarmored human, a chain shotgun can kill with 3 hits to the torso, 2 hits to the head or neck, or 1 hit to the brain; cripple or destroy limbs in 2 hits; and destroy eyes and digits with a single hit. It'll generally take around 4 hits (~6.98 seconds average) to incapacitate that human from pain shock.

Overall, the chain shotgun is best paired with a careful shooter up to level 6, then with a trigger-happy shooter beyond that point.

    Chain shotgun vs. comparable weapons[edit]

    This section goes over how well the chain shotgun fares against comparable weapons (similar value, tech level or similar characteristics) in 1 vs. 1 combat.

    Methodology[edit]

    • All testing is semi-automated which allows for large sample sizes to be gathered per set of results with ease
    • All pawns have skill levels of 14 in ranged and melee
    • No pawns have any traits that affect combat performance
    • All pawns are of at least 18 years of age and completely healthy
    • Pawns are divided by walls to prevent stray shots from skewing results in any way
    • Weather is always kept clear
    • No cover is used for either team

    Results in the tables below are the percentages of battles that chain shotguns either won or tied against the weapon listed in the first column of said tables, with a sample size of 2,000 battles per result. Higher percentages are better.

    Unarmored[edit]

    For the unarmored testing, all pawns wore normal quality plainleather pants, plainleather button-down shirts, plainleather dusters and plainleather cowboy hats.
