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.

The mightiest Alpaca to ever wield a machine gun. Don't ask. I don't want to have to explain KR server memes.

With all of the newer MGs she's just okay. Not bad. Just okay. May find a use for her, but eh. Maybe if she ever gets a mod...

Given the skill, one might be tempted to treat her like a normal AR with hilarious early burst damage, but you'd be dumb to do so, because she doesn't get buffs from SMGs and other sources that buff ARs. Also her crit rate is the usual garbage 5% MGs usually get instead of the much better AR rates, and she can't equip PEQs.

That said, she can be a fun mix if you, say, happen to need AR formations to punch through armour (because she can use the absolutely bonkers MG unique ammo types)

She has a very weird and complicated set of skill interactions for a role that really just wants good, consistent dakka. Has a funny combo skill with M82 (the bullpup AR, not the RF). In terms of performance she's actually not awful, but she doesn't stand out, and there are enough good ARs to use other than her.

On one hand, she's actually not bad in melee. On the other, she suffers from dumb mechanics (like not being able to switch to melee while reloading, which WOULD HAVE BEEN REALLY NICE). She's not terrible at the role of "melee shotgun" (she's actually quite good at it), but the number of situations where you'd actually want a melee shotgun are quite limited.
