Fortnite fans can unlock tons of cosmetics for free as part of the Rainbow Royale event, but the items won't be available for too long, so gamers must act before they're gone. Fortnite's Battle Royale game mode has been around for nearly six years, and throughout this time, thousands of cosmetic items have been released. Gamers can fill up their lockers by making purchases in the Item Shop, acquiring packs, completing the Fortnite Battle Pass, and participating in events. So, even though many cosmetics can only be purchased with V-Bucks, it's also possible to get tons of free stuff in-game.
