Loot builds up fast in ARC Raiders, and the default stash capacity doesn’t keep up for long. The game does let you buy more space directly from the Inventory screen; you just need Coins and the right button.

Stash vs. backpack capacity

Storage Default slots How you increase it
Backpack (during runs) Varies by Augment (e.g., Looting Mk.1: 18; Combat Mk.1: 16; Tactical Mk.1: 15) Equip a different Augment or craft a higher-tier one
Stash (in Speranza) 64 slots Buy permanent slot upgrades from the Inventory > Stash screen
Tip: In Stash, use sorting to triage items, and the “Unload Backpack” action to dump everything you brought back in one click.

Expand Stash: where to find it and how it works

  • Open your character’s Inventory in Speranza and switch to the Stash tab.
  • Look near the top-left of the Stash screen for the Expand button.
  • Press it to see the purchase prompt, which shows the cost in Coins and how many slots you’ll add.
  • Confirm to buy. The new capacity applies immediately.

Each upgrade adds a fixed block of additional slots, letting you stockpile more weapons, materials, and schematics between runs.

Stash upgrade costs and slot gains

Upgrade tier Cost (Coins) Slots added New Stash capacity
First 5,000 +24 88
Second 10,000 +24 112
Third 15,000 +24 136
Note: Later tiers and pricing may change with balance updates, and some players report different values at higher levels. Always verify the on-screen purchase prompt before you commit Coins.

When to buy and how to fund it

Buying Stash space early pays off. You’ll bring home more per raid, finish materials quests faster, and avoid the churn of recycling or selling mid-craft. If Coins are tight, prioritize one or two upgrades first and then ramp up as your extraction success rate improves.

  • Short on room mid-run? Dismantle low-value junk to free backpack slots.
  • Back in Speranza, sell unneeded items or recycle extras into components to keep Stash tidy.
  • If you’re doing quick, low-risk farming, consider loadouts that favor backpack space so you can feed your Stash efficiently.

The key takeaway: your Stash starts at 64 slots, and you can expand it right from the Inventory screen using Coins. Hit Expand, buy the upgrade, and keep the +24 slot cadence in mind as you plan purchases. The sooner you unlock a few tiers, the smoother your crafting and trading loop becomes.
