So what rocket launchers are the best and what for

[Chadstream Onion]

Spear: Taking down heavy armor enemies (Tanks,Automatowns respawn thing,Bile spewer)
So its basically an item to do objectives and taking down heavy armors But not Bot dropships, it toggles onto middle of them instead their engines
Recoiless rifle: For taking down medium Armors and Dropships and clearing bugs nest
its not that great to fight against tanks and heavy armors, it doesnt provide that much of damage and splash area
Airbust: uh... i have still lot of questions how does that thing work. but still you would get more helldiver kills than actuall enemies with it.
Expendable rocket launchers:Pretty good and 70s cooldown rate you can spawn a lot of it, its good for everything, it has 1 use only so you gotta hit your shots (or nail your neighbour dog)
Laser cannon: medium armors generally i personally dislike it
Quasar cannon: Best for medium and also heavy armors it has looooong cooldown its alright tho.

I found the airburst really shined when I went from 7 to 8. When you get even bigger crowds the ability to just annihilate everything in an area is incredibly useful. It's also possibly to wreck hulks and chargers with it if you can get it to explode around their butts. I haven't used it enough to become proficient, but having a shoulder-fired rocket that nabs 60+ kills and takes out a charger in one rocket every now and again can be really helpful.

But yes, it is still one of the most effective ways to eliminate fellow helldivers.

I used it only when it was avaiable to everyone, it was buggy a lot and had absurd wall hitbox
