In the apocalypse trade goods are used as the currency to buy special items, like crates, radio phones and hero tokens.

You can start collecting trade goods after reaching council level 7 and setting up your outpost.

You get trade goods by raiding other player’s outposts and collecting stars during challenges. Additionally, your outpost building produces a small amount of trade goods.

Trade goods are used in the trade goods shop that you can access through Shop > Trade, or directly from the outpost through “Get Rewards”.
