Actually good for the same reason WA-2000 and M14 are. Sheer RoF with decent damage. The only 4 star rifle worth using by default who does not require you to jump through hoops to even matter.

The Chicago typewriter, the classic mobster gun (ignoring the fact mobsters actually used M1918 BARs most of the time for actual hits), and TaneRisa-chan proving that even as a gun, she protects us. Highest HP among SMGs but conversely has abysmal evade. Has a very good invul skill though, and is a solid tank overall, though she'll need a lot of repairs after every mission.

CAPTAIN CHINNNAAAAA! Surprisingly good for a free unit. Has the lowest armor among the shotguns (tied with Super Shorty), but she will get you started considering how easy it is to get her. Aura optimized for 1SG/1HG/3MG setups, and works well with Mk23 and M2HB (which are both given for free to new players too). Has a very tiny 3-shot magazine compared to the usual 4 most SGs get which limits her firepower somewhat, but her skill offsets this a bit. A flawed unit and not a first pick for many lineups, but most SGs are interchangeable as far as front-row tanks go anyway, even if she's not as good at it as the other ones you'll get eventually. Her main merits are a decent aura shape and being free.

She does have a mod which...kinda makes her better? Will add that article soon...probably.

Called "The Northern Hemispheres" for fairly obvious reasons. Somehow, someone decided "Featherlight" clearly means "biggest tits on a t-doll possible." Her skill lets her do a bit of damage except you dont care about that sort of thing on a shotgun and its not like the skill has time to trigger on a typical fight (most SGs dont get to use their skills anyway). Still, well... she's a shotgun with 22 base armour. This puts her ahead of the lower end shotties like supershorty.

Despite having the lowest armor among the shotguns (tied with Captain China), her skill offsets this a bit. Also has the lowest HP among the 4 star shotguns though, but whatever, she can still take hits. Her main downside is the shitty aura, but she can at least do the job of eating hits.

AKA, SHARK-CHAN. Shitty aura shape, workable buff. Has surprisingly high HP for a 3 star shotty, and surprisingly ok damage, otherwise average tanking ability. With the release of better SGs, you'll want better if you can, but all shotguns are at least usable if you lack anything better.

Her unique makes her slightly better offensively, but still far away from being actually good at it, and 90% of the time you want your shotguns to tank.

MURRICAN SHOTGUN. The most usable aura of the 3 star shotguns currently on EN, though forcing her to be in an offtank position. 21 armor and a +armor skill. There's really not much to say about most of the shotguns besides "they'll do work if you really want them to."

Also a better catgun than IDW. IDWSG DA NYA.

She also has a mod, and the review for that can be found here.

Actually has one of the highest evade ratings among the SMGs and posseses a skill with really good uptime (15/16!), but kinda eh tile buffs. So why just "usable?"... Because other SMGs exists, and does it better in every way. In addition to having other features that make it better like being able to increase damage or accuracy or evade passively, permanently, and it is very hard to recommend her knowing that something superior in every way is kinda... you know, there.

A pretty decent SMG with a stun grenade that lasts longer than base UMP9's. Her tiles wants her to be the main tank, also her buffs are actually quite nice (+20% firepower) for ARs. Mainly suffers from stun grenades being less than useful against bosses and the fact other, better SMGs exists. In fairness, UMP45's existence makes a lot of SMGs less appealing in general, but her 4.5s stun has some potential uses (Golyats).

While her exclusive is good, it doesn't really change much about her performance.

Pretty much a 4 star LWMMG. Has Hunting Impulse, which is basically the 2nd best non-unique MG skill. (But there's absolutely insane unique MG skills, so that's not saying much anymore) Has slightly lower firepower than LWMMG, but has 1 more shot in the mag to make up for it.

Similar to G41 in performance (actually slightly worse, but not significantly) and the artist just drawing their weird fetishes that land you in jail. She's basically a 5 star equivalent of Tavor sharing the primary weakness of taking 6s to startup instead of 4. The skill is good while active, but YMMV.

Honestly, the issue with any AR outside of the big mod ones, is that they just get gapped so hard unless they have a niche. ART556 does not. So you could use her, but....eh...?

Extra notes available.

She's still usable and good enough to deal with older content just fine, but the new shotguns currently available just blow her out of the water so hard. Sad day to be a pizzalion.

That skill happens to be giving your entire front row a 35HP shield, that takes armour into account first. It also has 5/8 uptime. Basically, if your SGs took scratch damage before? They should take literally nil now, unless its a really major fight or you were silly enough to go fight anti-armour enemies.

Unlike the other shotguns, she's focused on firepower instead, with her skill basically making her go DAKKADAKKADAKKA. You would want an Acc scope on her so she can actually hit anything. Sometimes used in 1SG/1HG/3MG formations to provide MAXIMUM FIREPOWER. Tiles are a little eh for that though. Armour is average.

Usable I guess? Really, one of the lower end shotguns, but she can still tank. Just not a first choice when you now have actual choice in shotgun variety. Doesn't do anything badly, but doesn't really excel either. Does have decent offtank tiles though, if you want to run 2SG.

Honestly would be fodder but she has a decent enough tileset if you're lacking in HGs with FP boost. Gets considerably better in her mod form, which improves her tiles immensely.
