Atomfall features a barter system instead of traditional currency, which is befitting of its action-survival setting where you are trapped in a quarantine zone. Simply put, the game relies on trading goods rather than a typical monetary system. Many players may be unfamiliar with this mechanic and could wonder how or where they will first encounter it.
This guide details the barter system and explains how to use it effectively in Atomfall.

How to use the barter system
The barter system functions through direct item exchanges between you and a trader. When you initiate a trade, an on-screen barter menu appears with the following:
- Left side: Displays your inventory.
- Right side: Shows the trader’s available items.
- Centre: A balance scale that measures trade value.
Adding items from your inventory tilts the scale downward on your side. To balance it, you must select items of similar value from the trader’s inventory. Some trades may require multiple items to match the value of a single high-worth item.
- If the balance scale is even, the trade can proceed.
- If you overpay (offering more valuable items than you receive), the trade is still allowed.
- However, if the trader’s items exceed the value of your offer, the trade cannot be completed.
Additionally, different traders value certain items more, allowing you to negotiate better deals when using those goods.
