M39 is my current favorite, AP mags, reflex, stock, laser, even one handed you get decent enough accuracy for what my favorite thing to do with it-- putting on B12, running up to a T3, and standing behind it while marines shoot it. If you pull off a bodyblock with this thing and dump an AP mag into it, unless the other marines with you are hilariously bad, itâs dead. Being able to put the m39 belt with the extra mags on your armor slot to carry a little extra ammo is very nice for ammo-space scarce roles like CT or medic. M39 also has the benefit of imo being one of the few available primaries with enough DPS to chase lurkers and runners off without having to bring a second shotgun. Easy S, super underrated, only downside is the ammo eco-- you canât carry that much ammo (unless you go ammo box), the flip side is not as many people use it so you almost have full boxes of AP mags to refill from at FOB.
MK2/MK1 is probably just under that, especially with a UBS you get a lot of utility from these with not a whole lot of space used, definitely the âjack of all tradesâ and is pretty useful for every situation(though personally I struggle to make runners and lurkers disengage with this if they target me.), these are an A.
M240âs also probably around A, in the hands of a well paid xeno agent these can completely ruin pushes, but defensively and during sieges especially, the flamer is a âfuck you, you cannot be hereâ to every caste but 2. incredibly strong.
HPR is similar in the area denial role, and has the bonus that unlike the flamer with itâs somewhat lackluster DPS on itâs own, a well placed HPR ambush can nearly instantly drop a lot of castes, this would be an S tier if it was able to load AP ammo. HPR has the benefit over the flamer of not completely griefing the front if you use it right, but has a bad reputation because of people setting up the bipod in the middle of marines and spraying FF. A tier.
M4RA is hard to place, statswise itâs pretty good, however imo itâs not viable in terms of ammo eco without taking an ammo box, which sacrifices your chance at a full secondary, and unless your aim is very good getting targeted by a backliner is a death sentence. the fast wield and run speed + damage with it makes it a pretty solid chase gun, but usually spraying bullets with an automatic weapon ends up helping the team more. L42A is imo a straight upgrade since with a bayonet it has a higher tier of melee damage than an M4RA with one. B.
The MOU and M37 both serve a really useful utility in their ability to stun, but have suffered nerf after nerf over time, to the point theyâre usually relegated to a secondary support weapon. they lack the DPS to actually kill anything usually unless you have competent players with you to make good of the high burst damage they provide, and are irreplacable for making lurkers and runners think twice about going for you, and punishing them hard if they do. B tier
XM88 has a whackload of damage, but unless your aim is particularly good the scaling AP system is mostly a non factor. The gunâs also handicapped heavily by really bad RNG miss, meaning you are pretty much required to spriteclick to hit anything, even with attachments tailored to fix the inaccuracy. This gun can surprise xenos with a lot of sudden DPS, but generally I dont see people getting kills with this(except vs marines), I consider it more of a deterrent, a miniature version of the sniper specâs deterrent effect, xenomorphs are dissuaded from being as aggressive once they know thereâs someone with an XM88 who can belt off 300 damage on the spot when they overextend, C tier.
The GL is honestly, incredibly underutilized, but on itâs own you donât kill things with this, and generally itâs clumsy enough even with your hotkeys well memorized that it is only a team support weapon, taking a GL and a belt full of baton slugs as a secondary will secure many T3 kills for your team if theyâre competent, and itâs far more reliable for shooting stunnable T1âs and T2âs, since you can just blast through friendlies due to IFF and donât have to worry about hitting them. If you have a good squad, slapping a xeno with a baton slug is a death sentence. C tier
