Choco tabemase? You get her for free and she performs OK. Has a long history of suffering in the game and may suffer from PTSD. Damage bonuses are nice, and she's just strong enough to take down a Jupiter cannon by herself, provided you have some cannon fodder between her and the Jupiter (which is mostly why she has PTSD).

She used to perform really well, and she does perform OK for cost to raise, but a 5-star and 3-star AR cost the same to actually use, and the newer ARs are much, much shinier. She's still OK but don't get too attached, you'll have better soon enough. Maybe she'll get a mod someday.

Korea calls her "Ram-G" because pronouncing LWMMG as a word is hard, apparently. Performs like a 4star. MK48 has the same skill as her, in case you want an upgrade later down the line. Good stats marred by low max ammo count. Probably more useful than most of the 3 star MGs.

She has a mod now, which you can see here
