Like every other DPS shotgun, she really doesn’t have a place in current content. A phrase commonly used around here is “a solution in search for a problem”, but the real problem with MAG-7 is that I’m not entirely sure she’s a solution either.

Her passive effect can be very nice when enemies start having 600 armor, but the times there are less than three targets are very rare. Her active skill can make her damage go sky high if it’s allowed to stack, but her being on the frontline gives her the same issues a lot of DPS SMGs have. She’ll lose links, cutting her damage by a ton. Not to mention that it takes a little while for it to ramp up. The DR afforded to her by the skill isn’t high enough to keep her healthy enough to do much.

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.

Yes I know that's not really her name. And yes, you'd think the unit whose hands are actual guns would be a handgun, but nope, she's an SMG. MICAAAAAAAA.

She has a pretty interesting skill that reminds some of C-MS. What it is is mildly more complicated, because it comes with good AND bad sides, and allows her to be both a main tank and an off tank. As an off tank, she provides decent firepower with 100% uptime, a debuff no one cares about (-acc) and a really nice buff (constant eva up!) for the main tank, while as a main tank she has permanent Eva up, buffs acc of the same column ("vertical row") but actually makes the off tanks (or just people in the same column) a little less survivable. Skill discussed in more detail in her entry, but its fun stuff.

A problem she has though is the shape of the tiles. That lacking middle row really gets in the way, but she has enough other uses that this isn't too awful if you know what you're doing (For example, you want to buff the everloving bajeezus out of your main tank's dodge instead).

Also she buffs Rifles with her tiles too too, but this doesn't seem to come up all that much.
