Back 4 Blood features a number of Cleaner and weapon skins to unlock, and there are various ways you can do it. Released on the 12th of October 2021, Back 4 Blood is the latest title from Turtle Rock Studios. Although it is the spiritual successor to Left 4 Dead, it brings enough innovation to stand out and feel new. There are eight Cleaners you can play as when you take on hordes of undead known as the Ridden. If you want to customize your Cleaner or your weapon, Back 4 Blood offers an assortment of skins. However, you are going to have to put in a little effort to get them.
How to Unlock New Cleaner and Weapon Skins
To unlock skins, you first need to rack up some Supply Points. Earning Supply Points is as easy as playing through the campaign missions. However, it should be noted that you will not earn Supply Points if you play the solo campaign. The higher the difficulty you have chosen, the greater the number of Supply Points you will earn for each mission. Supply Points can also be earned by achieving in-game challenges called Accomplishments. Some Accomplishments will net you some Supply Points as a reward.
When you have racked up a good number of Supply Points, you can spend them at the Supply Lines vendor. You can find the vendor sitting at a table back at Fort Hope. After approaching her, you will be able to spend your Supply Points and complete Supply Lines. Each of the Supply Lines offers cosmetics and cards for you to unlock. To unlock an item in a Supply Line, you have to unlock all items prior to it. For more information on Supply Points and Supply Lines, Attack of the Fanboy has a convenient guide.
Some skins are hidden behind Accomplishments. You are going to have to work very hard for them, however. For instance, there are full outfits for the Cleaners that can be unlocked by completing 250 missions with each Cleaner. Hence, to get the Trail of Blood outfit for Walker, you will have to complete 250 missions as him.
The last way to unlock extra skins is by purchasing the Ultimate Edition of the game which comes with the 4 Character Battle Hardened Skin Pack.
Back 4 Blood is available on PS4, PS5, Xbox One, Xbox Series X/S, and PC.
