Turtle Rock Studio’s latest game, Back 4 Blood, returns to the studio roots for cooperative shooter action. Players team up to take on the Ridden, a mutation caused by a virus that Back 4 Blood’s Cleaners specialize in exterminating. Along the way, players amass Supply Points as compensation for their efforts, but what can players use Supply Points on?
Supply points are Back 4 Blood’s currency system and can be used at the Supply Lines vendor to purchase Cards and cosmetics. Each of the game’s Supply Lines has eight tiers that players must work through entirely from start to finish to earn all rewards. Players cannot pick and choose rewards at random.

Certain Supply Lines focus on improving a single attribute of a character’s kit. For example, the Furnace Supply Line boosts player constitutions with offensive and defensive ability cards. Those aiming to optimize their deck for a specific playstyle should read the description of each Supply Line before spending their hard-earned points.
Back 4 Blood is available now for PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and PC starting at $59.99.
