What to Keep and What to Sell

Intermediate7 min readUpdated July 6, 2026

Loot is the point of every run: grab vital items, bring them back to your walker, and extract. When you return, though, it's hard to know what to sell and what to keep for upgrades.

The most common crates hold valuables, ammunition and weapons, food, shells, and medicine. Food, ammo, and medicine crates all contain materials you can use for upgrades and extract with.

What to Keep for Upgrades

You'll find a huge variety of materials as you scour Sophie. Below is a full breakdown of the upgrade materials that feed your tech tree and Trampler, and where each one comes from.

What to Sell and Where

Of all the crates you loot, valuables give you the most tradeable items - Small Valuables, Valuable Papers, and Crowns. Crowns are the primary currency in SAND, so keep those; the rest is your income.

Valuable safes are the most straightforward source of income for you and your team, which makes them a must-have priority. You can never have too many boxes of items from a valuables safe on your walker.

Everything has a price, though. If you're in a tough spot after a few bad rounds, it's worth selling a handful of resources you don't need right now. You can always return to Sophie and get more.
