With Back 4 Blood finally released, players can enjoy the co-op shooter with up to three friends and take down hordes of Ridden along the way. While there are a lot of things that players can unlock while playing, a lot of them cost Supply Points, so how can users earn this resource? Players can earn Supply Points by playing each of the game modes. Completing levels grants players more Supply Points, and the better the players perform, the more Supply Points they get. Completing a level grants players significantly more supply points than failures, so those interested in this resource should play to win.
