There's not really much to say about SSG...She's literally a 4 star version of M200. What do you want from me?

The main use she has is for no-dupe players or using her in SC ranking where she has a map bonus.

Everyone's favourite White Knight! (Unless you like Tim better, you weirdo.) Same tiles as Grizzly (literally the same), but with a defensive skill instead of an offensive one. She only shields Shotgun, SMG and HG dolls so it isn't full coverage (unless you're an all HG team anyway), but the ability to shield something like KSG is nice. Her shield actually scales based on how damaged a unit she's shielding is, but the exact formula remains a mystery (less HP = more shield though).

The Steyr ACR is the gun the Pallet Rifles in EVA are based off of, and this one is about as useful. On one hand, it seems like she'd be good for para fairy and its debuffs (you get +25% final damage with that), except it isn't enough to make up for the debuffs still. It's also not very easy to get debuffed. Evaluation may change based on future enemies, but really it's not worth it when you have so many good ARs to choose from.

One of the best login dolls, although not one you'll regularly use. Her skill gives a massive 40% FP debuff to enemies, making her a choice pick for doing things you're really not supposed to be doing. Combine with another FP debuff for better uptime to make it extra spicy.

Keep in mind that her skill works best at night.

Quite useful, but not great on her own. Her own DPS isn't especially impressive for an MG, but she can give a decent amount of extra ammo to other MGs, which can be worth it or not depending on who you pair her with, in addition to giving shotguns extra armor.
