Back 4 Blood Supply Lines: What Are Supply Lines?

Back 4 Blood Supply Lines is the system used to reward players for their efforts in Back 4 Blood. Supply Lines work sort of like a Battle Pass, unlocking progressively on a track. Each Supply Line is unique with a series of eight unlockable rewards. These rewards include cards, Cleaner skins, and other cosmetic items.

Completing the Back 4 Blood campaign and Swarm levels, along with the various challenges assigned to you in each run, will net you Supply Points. 

Back 4 Blood players can then spend their Supply Points on Supply Lines. In the Fort Hope hub area, there is a woman sitting at a picnic table who offers Supply Line services. Speaking with this woman will allow players to access their Supply Line progression.

In Back 4 Blood, players cannot individually select which rewards they want to unlock with their Supply Points. That is what Supply Lines are for. Each Supply Line contains a series of unique rewards. Unlocking rewards in a Supply Line becomes increasingly more expensive with each purchase in a sequence. Once a player unlocks the eighth and final reward in a Supply Line, a new Supply Line will take its place.

After completing the starter Supply Line, players are free to pick and choose from an array of different Supply Lines and determine which subsequent Supply Line to progress. Starting a Supply Line does not lock you into that select Supply Line permanently; you can go back and forth progressing different Supply Lines as they see fit.

Back 4 Blood players cannot purchase Supply Points and Supply Line progress with real money, thankfully it's all in-game progression. The same goes for how to unlock characters in Back 4 Blood.
