Heavy SMG

The heavy SMG is a moderately heavy, multi-shot ranged weapon that 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[edit]

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 or obtained from the following raider kinds:

Raider Kind	Chance	Average Quality	Health
Town Guard	6.09%	Normal	60-200%
Mercenary Gunner	14.62%	Normal	70-320%
Ancient Soldier	11.40%	Normal	100%

Analysis[edit]

The heavy SMG is a flexible, but close-quarters focused offensive weapon. Its accuracy makes it very friendly towards low Shooting skill users.

Specifically, the heavy SMG combines good low-range accuracy, decent rate of fire, and high per-shot damage to make an overall effective weapon for any skill. At said ranges, it will outdamage the machine pistol, assault rifle, and even the charge rifle (for up to 10 cells). It's worse than the chain shotgun at close-quarters fights, but has a greater max range, making it more effective for general firefights and flexible overall.

Range, though not as short as other weapons in its class, still leaves a little to be desired. Similarly to the machine pistol, the heavy SMG's stopping power isn't high enough to stagger humans, only small animals like tortoises and boomrats.

Stats[edit]

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.

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

Comparisons[edit]

Comparison to assault rifles[edit]

Heavy SMGs and assault rifles are preferred weapons when it comes to "general" combat. The main differences are that the heavy SMG is cheaper and better at short range, and the assault rifle is better at medium-long range.

Specifically, the heavy SMG is better until 13 tiles, regardless of Shooting skill. The assault rifle is better past 13 tiles, regardless of Shooting skill. This is true for the vast majority of reasonable scenarios.^[1] The reason the heavy SMG is "skill-friendly" is that a low-skill shooter will be next-to-useless when firing from far away, no matter how accurate their gun is. An unmodified, skill 0 pawn has a 5% chance to hit from 25 tiles, which is then multiplied by x35% for a normal quality HSMG or x65% for normal AR (at this range).

The assault rifle has a range 8 tiles longer. This allows the assault rifle to comfortably outrange enemies like tribals, termites, and centipedes. The assault rifle dominates for kiting tactics, or if you're repelling breachers from a distance, or in a firefight when both parties are attacking from max range.

Therefore, whenever heavy SMGs or ARs are better will depend on what you are looking for:

In a killbox, both weapons perform roughly the same, as you can change the length of the killbox to compensate for your weapon of choice. In a pure killbox scenario, Heavy SMGs are often the preferred weapon, as they are significantly cheaper. (When using an SMG killbox, give yourself a bit more than 13 tiles of range.)
Outside of a killbox, but in a defensive emplacement, the superiority depends on shooting accuracy.
- Assault rifles are better for higher skill shooters. They are a lot better at medium-long range, so are a lot better in an overall firefight. Only skilled shooters are competent at shooting at this range.
- Heavy SMGs are better for low-skill shooters. HSMGs are better against melee attacks, which shooters of any skill can help with. They are also better against sudden drop pod raids and infestations, due to the close-ranged nature of both fights.
- Note that the chain shotgun is the ultimate short-range weapon, for both low- and high- skill shooters. However, the heavy SMG allows low-skill users to at least try to fire at long range, providing some help, and eventually training up the Shooting skill.
If relying on offensive or otherwise mobile tactics, the assault rifle is a clear winner regardless of skill due to its range and accuracy at longer ranges.

Notes:

¹ When fighting larger targets, like centipedes, it is possible to cap at 100% accuracy with assault rifles. This requires a high quality weapon and an great shooter. As further shooting bonuses (masterwork/legendary weapons, bionic eyes, luciferium, shooting specialist, etc.) would boost the heavy SMG but not the assault rifle, this would make the SMG better than the AR from a longer distance. However, assault rifles still have a superior max range.

For human targets, reaching the accuracy cap should be impossible unless the Combat in Darkness precept is used in darkness.

Graphs[edit]

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.
