Fortnite just held its Fortnitemares Finale event, and the five-minute affair made major changes to the Battle Royale map. Kevin the Cube has finally been destroyed, and his Rift energy caused a new group of rocky islands to appear in the center of Loot Lake or Leaky Lake. When players captured a butterfly inside the Rift, they were teleported to the new map. With the details still unfolding, players are currently working to uncover any other secrets the event may hold.
