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.

The most German unit in the game, in that she is both exceptionally lazy and surprisingly good at her job whenever she can be bothered. The source of 90% of HK416's misfortune. Zombie movie afficionado, and owns all 26 seasons of The Flying Dead (Im not making this up.) Originally one of the most broken ARs in the game until digimind evolution and team DEFY showed up. First member of Club "MGs who pretend to be ARs." Max out her skill, point and laugh as she destroys everything. Skill has poor uptime which makes her worse than AN94 in 90% of situations (and arguably worse than STAR Mod3), but still pretty good.

Her skill is completely useless against armoured enemies, which will become an issue later, when more and more armoured enemies appear.

And then her mod comes and she is a fucking god because it solves basically everything.

Kind of fetishized and sort of jailbait, but she's still a very solid option if you have her special equipment. Outside of that, she's pretty mid. She used to be the standard ARs were judged by, but now she's pretty irrelevant.
