Turtle Rock Studio's latest game, Back 4 Blood, returns to the studio's 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 specializes 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 monetary system and can be used at the Supply Line Vendor to purchase cards and cosmetics. Each of the game's Supply Lines has eight levels that players must complete from start to finish to earn all the rewards. Players cannot randomly choose rewards.

Some supply lines focus on improving a single attribute of a character's kit. For example, the oven supply line improves player builds with offensive and defensive ability cards. Those wishing to optimize their deck for a specific playstyle should read each supply line's description before spending their hard-earned points.
Back 4 Blood is available now on PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and PC starting at $59,99.
