Purchasing Battle Pass for Fortnite Season 7 unlocks face-swapping alien Kymera. The purple-colored alien has tons of customization options (head shapes, eye and skin colors, patterns, and armor colors). To unlock the various customization options you will need to collect Alien Artifacts.
Five alien artifacts can be collected every week. The artifacts are glowing purple rocks inside a glass tube. The location of the artifacts is random and can be a bit difficult to find.
