While exploring the wasteland and liberating trading posts, you will discover an array of vital resources and expendables designed to assist you on your journey. These items range from common market currencies to rare combat keys, each playing a specific role in advancing your Trade or Fight progression tracks.

To make inventory tracking easy, all in-game resources can be classified into four distinct utility groups.

1. Main Currencies

 
Coins: Your primary currency used within the main Trade Mode and limited-time events. Use them to hire workers, upgrade outpost buildings, and buy income boosters.

 
Gems: A rare, premium resource spent directly within the in-game store. Gems can be used to purchase speed boosters, grab gear chests, acquire vouchers, or buy permanent utility upgrades in your Safe (such as Speed Booster, Bedtime, and Scavenger's Luck).

 
Diamonds: A premium, specialized resource used directly in place of real-world money to complete store transactions.

2. Looting and Shovel Tokens

 
Shovels: Specific operational items required to search for and loot useful items that help you fight off zombie waves.

 
Tier Coins: Earned automatically from duplicate skins and spent strictly to upgrade your Shovel Handle to uncover higher-tier cosmetic skins.
