Heavy SMG

The heavy SMG is a moderately heavy, multi-shot firearm in RimWorld which fires 3-shot bursts of rounds which deal a moderate amount of damage each; a moderate delay between each shot; a moderate time between bursts; slightly shorter range and moderate overall accuracy. Recommended for low skill shooters.

Acquisition

Heavy SMGs can be crafted at a machining table once the Gas Operation research has been completed; from 75 steel, 4 components and 24,000 ticks (6.67 mins) of work. A crafting skill of at least 5 is required.

They are also commonly carried by Outlanders and Pirates and sold by traders.

Analysis

The heavy SMG has good short-distance accuracy combined with a decent overall rate of fire and high per-shot damage for a burst-firing ranged weapon. Damage output as a result of the aforementioned factors is good, being higher than the machine pistol, and even the charge rifle when within 10 cells - though the chain shotgun still has an edge. Due to the accuracy profile as well as fairly high rate of fire, the heavy SMG is a skill-friendly weapon, meaning that low shooting skill pawns can still effectively utilize this weapon.

Projectile speed is slightly slower than that of weapons such as the autopistol, pump shotgun and machine pistol, though the heavy SMG's overall rate of fire is low enough that the projectile speed's impact on overall damage output is fairly limited.

Range, though not as short as other weapons in its class, still leaves a little to be desired; weapons such as the LMG still hold an advantage in this area. Similarly to the machine pistol, the heavy SMG's stopping power isn't high enough to stagger humans or human-sized mechanoids, instead being limited to small animals such as tortoises and boomrats.

The heavy SMG is best used as a close-quarters offensive weapon as this role takes full advantage of its strong close-up damage output. Practicality as a hunting weapon is fair, though not brilliant due to its low stopping power and slightly shorter range.

Against an unarmored human, a heavy SMG can kill with 4 hits to the torso, 3 hits to the head, 2 hits to the neck or 1 hit to the brain; cripple or destroy limbs in 3 hits; and cripple or destroy eyes and digits with a single hit. It'll generally take around 6 hits (~8.8 seconds average) to incapacitate that human from pain shock.

Overall, the heavy SMG is best paired with a careful shooter up to level 13, then with a trigger-happy shooter beyond that point.

Graphs

The graphs assume a normal quality heavy SMG against an adult human that's out in the open in clear weather. For DPS, projectile speed has also been factored into the equation, with the weighting based on the base amount of attacks that it'll take to put the aforementioned target into pain shock.
