In Arc Raiders, coins are more than just numbers in your inventory — they’re the key to strengthening your arsenal, expanding your capabilities, and surviving longer in high‑risk missions. Earning coins is part of the core gameplay loop, whether you’re looting valuable trinkets in Buried City or selling unused materials after extraction.
Once you’ve built up a healthy coin balance, knowing where to spend them wisely will help you progress faster and enjoy more success in raids. Below is the start of a guide to the smartest places to invest your hard‑earned coins — from useful upgrades to critical purchases that make every extraction run count.

| Items | Description |
| Stash Expansion | Increase your inventory capacity, the most valuable long-term investment. Stash expansion isn't sold at a vendor, but is instead purchased on your own from the inventory menu. You'll initially start with 64 spaces in your stash, but this limit can be upgraded several times. |
| Upper Level Guns | Be on the lookout for timed sales to grab the best (but also most expensive) weapons possible. While this is no small chunk of change, purchasing something like this and then upgrading it as far as you can at the Gunsmith station will almost undoubtedly result in a much easier run the next time you go topside. |
| Upper Level Shields And Healing Items | Stronger medical gear and shields for high-level runs. These things can be improved further if you drop the required coin on some of the premium variations that Lance sells in his clinic. |
| Upper Level Augments | Advanced augments providing more space and passive buffs. For example, the Combat Mk. 2 will restore one Health Point every five seconds if you've been damaged (with a 30-second pause after each time you lose HP, to be clear). Find a passive buff you like, and pull the trigger on a shiny new augment. |
| Raider Hatch Keys | Quick, safe extraction points for high-value loot. Sure, 9K is a lot to spend on this luxury per use, but it'll sometimes be warranted if you're holding onto a ton of high-level loot during a topside run and need to get off the map with no wait time from a more secure location. |
| Gun Accessories | These are things like extended magazines, or specialized grips and stocks for reduced recoil and improved reload speeds. Gunfights in ARC Raiders can hang entirely in the balance of the smallest of details, so simply being able to utilize a bigger mag or swap them out more quickly can be the difference between life and death in countless scenarios. |
| Base Level Augments | There are a few different types of augments, and they serve the incredibly useful purpose of altering the layout of your loadout grid. Many of them grant you additional backpack and Safe Pocket space, for example, giving you more room to safely bring back as much loot as possible after a run. |
| Base Level Guns | Starter firearms to ensure you always have reliable weapons. In the worst case scenario, you can always use a free loadout if you've managed to lose all your stashed guns after successive failed runs. |
| Basic Shields And Healing Items | If you want to have the best odds of extracting in one piece, stocking up on medical items to bring into a run can quite obviously make the difference between getting back home, and losing everything. |
| Explosives | Grenades and other explosives for extra firepower in tight situations. You'll know already if you're a player that thrives in the world of explosives, so your own personal use cases and desire to purchase these items will vary. Of course, it's never a bad idea to have additional means of destruction on hand for when you're low on regular ammo or need to make a big bang at once, so buying a few explosives to stash can go a long way. |
