Her Mod 3 unique equip is alright. It lets her punch through lighter armors, and otherwise is excellent at finishing off weakened enemies, rather than wasting full-power shots on them. This is usually a thing with rifles that don't quite instantly giblet their foes. Her tile buffs are pretty okay.

She's alright but not a priority.

She actually gets some fairly hefty stat increases in her mod, with Mod 2 hitting as much FP as M2HB. The issues that 2 stars normally face (low skill values compared to higher ones, etc.) are pretty solved thanks to being upgraded to a 4 star, and it also gives her extra base ammo which helps out a lot. Overall a cheap mod to get, and honestly you get a fair bit of value off even just Mod 1.

She's pretty much an all-rounder MG, and with the Mod 2 skill, technically you're not limited to just SGs, but uh... the shield values are so low otherwise that it only really helps armored things, though I guess some people might find a use for that anyway. MATH BIT: Her Special Equip actually isn't awful, but tbh you're better off with an EOTech in most cases.

Her original form can be found here.

Passively, she's Mk23 with better tiles. Regarding her active abilities, she isn't as nice as Mk23's straight damage upgrade for some, but better for others (such as fights with Grape that require her to shoot faster). They're similar but not interchangeable so you'll need to use the space between your ears.

Also she's kind of boring and has no easy jokes besides the Viking name, which doesn't suit her at all, so blah.

Babushka says not one step backward. Every seventh shot, she gives a damage bonus! Also, the thing starts active, making her one of very few buffers with a start-of-battle skill activation. Her first skill is still defensive in nature, and the percentages got bigger. She's actually useful in a number of situations, either for reducing enemy firepower in specific fights (usually Gundam or tank related) or just the straight DPS boost from the get-go. You only really need her up to Mod 2, but the Mod 3 art is cute.

Her pre mod form is here

Modded version of M1911

A really expensive trash cleaner.

Basically when she pops smoke, she then goes Alvin York and blasts away 7 times for extra damage, hitting the farthest enemy and working her way closer to the front with every shot. If there are no closer enemies, she just keeps shooting that one until someone else has gotten closer (either because its dead and thus a new thing is closer, or something ran ahead of it).

Note that while the skill has an ICD of 1 second, she doesn't actually start blasting away until 3 seconds in due to the throw animation.
