Fortnite Skins

Of course it is.

You can get Skins Free and other cosmetics like V-Bucks by completing new challenges that appear in each update patch.

You can also unlock exclusive Fortnite skins by being among the best in the tournaments held with the arrival of famous outfits like TheGrefg skin that was unlocked by being among the top 100 in the tournament the Floor is Lava for example.

Buying the Fortnite Battle Pass also gives you access to many Fortnite Free Skins but they are no longer free at all.
