Every bit as good as she used to be awful; this is quite a feat, since she used to be IMMENSELY awful. You can make a fairly convincing argument she's a better value mod than AR team these days. She's that good. She's a little hard to use, sure, but she has piercing on a rifle and all sorts of minor extras.

She does have the issue of "can't equip PEQs" and thus suffers as much as any other rifle at night, but a rifle capable of dealing with enemy clusters a la M4 is very nice to have in general. She gets very heavy use in rankings for a reason.

Ironically for a rifle with a night-oriented skill, she works best during the day, because yeah, that issue about not being able to use PEQs.

As a grenadier, she's fucking awful. It has less power than most grenades do, which is not helped by her shitty FP stat, and she doesn't even aim at enemies (she aims at points on the ground based on her location). This may or may not have value depending on what weird niche content might come up, but she's definitely not general use material.

G&K's equal opportunity things means even penguins are accepted, I guess. She has a finnicky, slow, and generally not reliable shield. On the other hand, her gimmick relies on having shields.

She relies quite heavily on outside shields if you want to use her gimmick, so stuff like SAT8 and LWMMG mod will come in handy if you want to do so.

However, while she has good armour, her HP is the worst of the 5 star shotguns, and she doesn't have particularly good tanking gimmicks. She's usable, but probably wont be your first choice unless you want to use her gimmick that badly for whatever fucking reason

With LTLX7000 being out, the main question asked of most shotguns is "are they as good as LTLX?" As for M26-MASS, she does her damn best trying to be. While LTLX has her SUPER dumb damage mitigation in her active skill, M26 has it baked in as a passive. If any damage she takes is 5 or lower, it’s completely ignored, as if she had very good flash rounds. This is applied AFTER armor mitigation AND flash rounds. With flash rounds, she’s essentially immune to anything 8 damage or lower, which is very strong. However, if the enemy does too much damage, this passive does nothing. However, in current day, LS26 exists. This fixes damage taken to 5 which, spoiler, is negated by MASS's skill. Can be very strong to force MASS to tank some insane things. How often will that be used? Eh. It's neat at least.

The one thing she does have going for her with her passive is that she can actually mitigate damage that bypasses armor. You can entirely mitigate stuff like grenades through it. You could sit in gundam range for a bit and not fussed about it. You could even sit in Typhon lasers and be fine. (Depending on firepower of Typhon, please do not attempt without consulting a local doctor)

Overall, she does fall short of LTLX just due to the sheer power of doubling your armor along with 20% DR. The utility of her active also is less relevant compared to LTLX. Removing HP shields and buffs (which get far more common) is stronger than a Molotov and DR to backline. To add to that, the 6 second initial cooldown hampers the effectiveness of the backline portion of the skill. This is because most things that do target the backline would already be skullfucking you at that point. Other cases this is bad include maps M26 shouldn’t be brought to for one reason or another, like when shotguns are bad for it in general or you can’t use machine guns.

It's a shame she has voice lines now, since the best part about her mod was shutting up her annoying voice. But alas, you'll probably be hearing it, because unlike her basically not-worth-the-effort base form, this one is actually decent. The big change is the six second ICD, which lets her fire grenades within the lifetime of many fights in a meaningful way, unlike most other grenadiers.

This ironically makes her useless for Chapter 11 farming, but thankfully she's good for Chapter 12 farming.

The grenade itself is buffed somewhat, and the ICD also makes her a bit more stable than SOP for some fights (SOP retains the problem of "You need the enemy to still be worth hitting with grenades 8 seconds in"). Overall, decent grenadier that you'll likely use a fair bit for farming and events, helped by 416 playing a big role in a lot of event maps and thus getting stat buffed.

Oh, and get her equip when you can. it isn't stellar, but it beats the hell out of a frame that doesn't contribute to DPS.

i can't believe her fucking name is clukay

Proof that the universe contractually requires 416 to be a bitch, given trying to fix her shitty personality is what caused the problem in the first place. More hilarious is she's not even an HK416, but the Patriot Arms clone.

Instead of being a grenadier, she's basically a mine layer, planting mines that seem grenade-like, but the big thing is that THEY DO NOT IGNORE ARMOR. They do still do full damage to all units caught in the blast though.

She is however, pretty fast, taking only four seconds to use her skill for the first time, and having all three of her special gear means you start the battle with some mines in place already. This is potentially useful for something.
