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)

After literally years, M4 demonstrates WHY SHE IS THE HEROINE and becomes METAL GEAR.

She keeps all her old benefits but has 5 star multipliers and better stats now. This gets even better when Mod3 when she gets a unique that ups her firepower and ALSO gives her armour, so she can kinda tank in a pinch. Her buff tiles are ALSO slightly improved. Her mod 2 skill also tags enemies and enhances the mod skills of other Anti-Rain units.

The big thing however is the desperation mode. At mod2 onward, when 3 or fewer allied dolls are in battle (you can retreat 2 units to force this, or simply deploy her with a partial strength echelon), she pulls out the portable cannon and proceeds to deal hilarious damage that makes grenadiers wet their pants, as huge AoE blasts firing from every dummy. The blasts are kinda 100% accurate (the main hit can never miss, even at night, but the splash damage can. Its weird), and can partly crit (its complicated), and is meant to be a last ditch thing to save a fight under dire circumstances (of course, we instead abuse it). This is however, a doubled edged sword, as her RoF also goes down, so its possible for some enemies to slip by if you havent taken this into account.

Basically, Mod her first. She's pretty much priority #1 for modding.
