Helldivers 2

You generally find them in caches on the map when playing (highlighted beacons you can see from a fair distance). The super credits are automatically given to everyone when one person picks it up.

Technically, there's a way to farm these indefinitely by essentially replaying the same map. But you can't unlock the guns/capes/gear in each warbond without medals, which you can only get by doing missions.

Personally, I like the gameloop and how microtransactions are done enough that I don't bother with the "farm" since credits are so easy to gain overtime. The real grind is the medals and samples which you need a team to gather efficiently.

with medals? I don't think that's a thing.

super credits can be purchased using real money, or you can just find them in-game. it's always a good idea to sweep the map completely before extract.

You play the game? You usually find credits on most maps. Not huge amounts, but it adds up. Also, every warbond comes with unlocks that give you some super credits for medals.

It doesn't take nearly so long. I have about 100hrs of playtime and I've unlocked three premium warbonds without paying anything.

Each premium warbond gives you 300 SC (the free one gives a lot more), so the real number you need is 700.

Credit grinding can be done solo on any difficulty, and is pretty quick on the easiest (Trivial). No need to extract - once you pick up the credits you can leave. There are usually 20-40 SC per mission you can find. I did this for an hour or two (maybe 300SC worth?) but decided it wasn't worth my time. The vast majority is from playing with friends.

I think in a few years there will be too many warbonds to possibly grind out as a free player, but IMO right now it's fine.

Maybe you have the premium currency confused with samples? Samples are the upgrade materials that are a REAL grind, you need to extract with them to keep them, and they are not available from microtransactions at all.

I get credits all the time and I rarely crack hard

The other person covered most of it, but also, I'm at about 20 hours, only level 9, have mostly done solo level 1s with some 2s and a handful of missions with friends.

I'm around halfway through the first warbond and between what you can get in it and from missions, I have about 1200 super credits, at least 600 of which I got in mission.

(Edit to add: 5 to 10 per mission? You'll find multiple pickups of SC most missions and each one gives something like 10 so that's nowhere near accurate)

It is absolutely farmable. I know several people who've unlocked multiple premium warbonds without paying a dime, under level 30 and not no-lifeing it.

On top of that, nothing in the premium warbonds are significantly better than everything in the base warbond. You could never bother touching the premium warbonds and do perfectly fine.

Plus, these are not micro transactions. They're not pay to win, they're not predatory expendable items to boost a mission or something like that. If anything, they're micro DLC that you can fairly easily unlock just by playing.

I wonder if you've even been playing the game at this point because these are all things you'll figure out pretty quickly if you do.

Edit to add: I see someone responded and deleted their reply but it was something about how the other warbonds only give 30 SC each. That is completely inaccurate, they each give 300, with 100 in each unlock. This is incredibly easy to verify, all you have to do is log in, open the warbonds, and look. As for the rate of acquiring them otherwise, I refer to how long I've played and how many SC I've gotten in that time of very casual play. Just logged in to check and it's at 1160 SC, 550 of which is from warbond unlocks. So, no. It's not particularly grindy.
