Deep Rock Galactic: Rogue Core has a number of different enhancements spread across a deep skill tree that you gradually unlock by completing runs into the core. The choice you make largely depends on how you want to play the game: do you want to build a more defensive or offensive character?
It also takes quite a long time to unlock all the improvements and get them to their most advanced level, which requires a lot of progress. There's also no way to refund your choice once you've decided on a path. Here are what I consider to be the best improvements at the moment, just to give you an idea of what to go for.
Ammo pouch I
I went straight for Ammo pouch I. I have found ammo to be quite annoying in Deep Rock Galactic: Rogue Core. You can never really have enough. I experimented with just taking a gun to give you a 50 percent ammo bonus, but I would still regularly run out of ammo. This first improvement gives eight percent extra ammowhich it isn't, but we still want to go down this side of the tree.
I'm a Falconer main guy, which is why the enhancements I've chosen here are more aggressive.
Dealer I
To continue with the same theme (and to bring us down to the more aggressive side of the skill tree) I brought up Dealer I for bonus ammo when resupplying. Again, this is only a small five percent bonus, but sometimes even that small amount of extra bullets is enough to help you survive the next swarm.

Here is a complete beginner's guide for Deep Rock Galactic: Rogue Core.
Deadeye I
Next up, this is where we start getting some perks like make a meaningful difference to our claims production. Deadeye provides a significant 10 percent bonus crit damage. Now that you're on the go, you can start thinking more objectively about the upgrades you choose from REPDs and artifacts. More crit chance is a good place to start.
Bullseye I
Again, keeping with the theme, I picked up Bullseye very early to give you one small, small boost to crit chance (just two percent), but while this may not seem like much, it's basically a permanent version of the same REPD upgrades you get during a run. It stacks up, and later you'll still want to pick up the upgraded version of this enhancement.
Enhancements stack, meaning you can have Bullseye I, Bullseye II, and so on.
Impact frame I
You'll quickly realize that armored enemies are quite frustrating in Rogue Core. They are mushrooms lots of damage and the best way I have found to deal with them is to take specific armor destroying weapons and to pick up the different levels of the Battering Ram enhancement. It gives a 25 percent bonus to armor damage.
Ammo pouch II
This is the first level two improvement I picked up because I still found ammo management annoying, even if you have a Spotter on your team resupplying you. Ammo Pouch II only gives one extra 12 percent to your max ammo.
Retailer II
The same logic applies to Resupplier II. I actually ran Ammo Pouch I and Ammo Pouch II at the same time, as well as Resupplier I and Resupplier II to start getting some extended benefits of the improvements.
Sweet Tooth II
Next, I picked up Sweet Tooth II, not necessarily because I wanted to use this enhancement (although it can be quite valuable on the higher difficulty levels) but because I wanted to access the next line of enhancements, which started with Deadeye II. Sweet tooth gives extra healing from red sugar, the resource that you can find and mine to replenish your health.
Deadeye II
I kept the theme going with an upgrade to the Deadeye enhancement, which gives one bonus 15 percent crit damage. Now with Deadeye I and Deadeye II you have one bonus 25 percent critical damagewhich is a huge upgrade.
Bullseye II
And to finish off my first ten improvements I've chosen Bullseye II which gives one extra three percent chance to crit. Pair this with Deadeye and you start to see the right chalk build take shape.
