Helldivers 2

Sickle, for sure. If you pace your fire properly, it's got the best ammo economy out of any primary (outside of the Blitzer, maybe). The armor pen leaves a lot to be desired, but aiming in first-person is accurate enough that you can shoot around armor or target small weak points from afar with relative ease in a lot of cases.

Unless it's a hot planet and I'm expecting a lot of engagements, in which case I'll go back to the Slugger. It feels like overkill for most enemies, but damn is it satisfying to use. I especially love the Slugger's sound design, it's got such a satisfying "kachunk"y feel to it.

Against bots, Iove me some Slugger. Being able to stun lock the missle bots is just too good.

I’ve been having a lot of fun with the Sickle and Quasar combo. If you watch out for the heat you never have to worry about ammo.

Breaker for sure. Shit wrecks

Breaker Spray and pray for bugs.

Sicle and Slugger.

Liberator penetrator gang💪🏼, goes hard on semi auto

I’ve been using the punisher more recently as well and it’s very good too, has some surprising range

I know the devs have stated that they want the primary weapons to feel weak but I think they forgot to apply this balancing philosophy to the scorcher, breaker (+variants) and slugger. I use the scorcher myself just because it's more versatile than the others in the top tier but if the game were better balanced I would have been spamming the plasma shotgun, it feels so fun to use but it performs like a direct downgrade to the scorcher

Slugger and Counter Sniper.

Dominator, great single shot control of most medium and small enemies. I'm a mid/close range accuracy guy so it suits me well.

Grenade launcher and arc thrower ;-).

But seriously the breaker and the scourger are fun to play.

I've started using SG-8P Punisher Plasma. I am a big fan of just exploding wave after wave, though I still need practise with it.

Used Recoilless Rifle stratagem previously. But now I switched to Quasar Cannon which lets me use a Rover to help deal with melee. Considering buying the Senator for taking out un-armored targets at long ranges.

A fellow penetrator enjoyer! The medium armor penetration is just too damn handy. I've tried switching it up but I always end up coming back.

The slugger is probably my #2, followed by the regular sg225 (auto shotty).

Surprisingly, the scorcher with the SMG pistol and quasar cannon. A heavy loadout but against bots you can pull down a lot without getting overrun. Friends deal with the little crap haha
