Being rewarded for meeting certain criteria in a game is always a great feeling, especially when it comes to overcoming a challenging obstacle. In Back 4 Blood, these rewards aren’t overtly stated, but they have quite a few. For example, unlocking the Zwat skins for your purifiers takes quite a bit of time, skill, and patience.

To get a Zwat skin in Back 4 Blood, you need to beat every single level in the campaign on Nightmare difficulty with this cleaner. For example, if you beat the first few levels with Evangelo and come back with Mama and finish the rest, you won’t get Zwat for any of the characters until you go back and play those missed levels with each character. Earning this achievement on a character will unlock Zwat for that purifier only.
Completing all of the Nightmare levels will be a real test of skill and teamwork at first, but doing it with a character really shows how well you can handle them. Whoever you try to work with, make sure you have a team you can rely on with good communication. When you’ve completed all of the campaign levels on Nightmare with a character, open the Purifiers tab in Fort Hope Base and equip your new badass skin to show off your mastery of that character.
