The Gemini Skin is an Epic Fortnite Outfit from the Space Hop set. This cosmetic has been leaked, and the skin will hopefully be available to purchase in the near future! Gemini was first added to the game in Fortnite Chapter 2 Season 2.
Gemini was a leaked skin that had been found in the files during the Easter of 2019. It appears that this skin has been removed from the files and replaced by the Astro Assassin outfit.
How-to Get the Gemini Skin
Gemini was leaked or datamined, which means we don't know for sure how it will be released. Most cosmetics that are leaked will be released within 30 - 60 days of their discovery.
