Fortnite Chapter 4 Season 4 will be heist-themed, and there is evidence to believe that several known Mythic rarity weapons could be brought back to the game hidden inside locked vaults. Chapter 4 Season 3 will be over in a few days, so gamers need to make sure that they don't leave behind any unfinished business before this Fortnite season comes to an end. Once Season 4 starts, Season 3's Battle Pass will become inaccessible, the Break the Curse Jujutsu Kaisen event will end, and everyone's level and rank will go back to square one.
