Back 4 Blood Wiki

Copper(Copper) is the currency used in Back 4 Blood.
Players can collect copper to purchase useful items and weapon upgrades from a KSC Vendor Create at a Saferoom. It can also be spent on Active Cards that can be found scattered across the levels or be used to restore Health once all free charges of First Aid Cabinets have been used.

Copper can be found in many places across levels in varying amounts. Some places copper can be found are inside cars, buildings, or inside stash rooms. Once a player collects copper, that collected amount is awarded to all players in the party rather than being split between members. Copper can also be generated using Active Cards, Burn Cards or via the Corruption Cards that the Director will throw at the Cleaners.

Players can share copper by opening their inventory menus and drop copper in stacks of 100 or their entire copper at once.
