As part of today’s Back 4 Blood update, players can now jump into the solo offline campaign mode with progression and earn supply points, achievements, and other unlockables. All progression can be carried over to and from online campaign mode. The December 2021 Update also introduces “Roving Merchants” which are rotating, time-limited, supply lines that provide players with more rewards to spend Supply Points on.
