Back 4 Blood: How to unlock the Zwat skin cosmetics

It's always a nice feeling to be awarded for meeting particular criteria in a game, especially when it comes after overcoming a difficult obstacle. These incentives aren't explicitly stated in Back 4 Blood, but they do exist. Unlocking the Zwat skins for your Cleaners, for example, will take a considerable amount of time, skill, and patience. In Back 4 Blood, here's how to get the Zwat cosmetics.

To earn a Zwat skin in Back 4 Blood, you must use that Cleaner to complete every level in the Campaign on Nightmare difficulty. For example, if you beat the first few stages with Evangelo and then return with Mom to finish the remainder, you won't obtain Zwat for either character until you go back and play those levels with each character separately. Only Zwat for that Cleaner will be unlocked if the achievement is met with one character.

To begin with, completing all of the Nightmare levels will be a true test of skill and teamwork, but doing it with just one character will demonstrate just how skilled you are with them. Regardless of who you try to accomplish it with, make sure you have a team that you can trust and that communicates well. Open up the Cleaner tab in the Fort Hope base and equip your new badass skin to show off your mastery of that character if you've beaten every Campaign level on Nightmare with that character.
