Today is a big day for the Fortnite battle royale. Later today, Fortnite Chapter 2 will come to an end and will be replaced by Chapter 3, and while fans will have to wait for the event to happen at 4pm ET, leaks have given everyone a pretty good idea of what to expect. It seems as though the Fortnite battle royale map is getting flipped over, and on the other side is a brand new battle royale arena for players to fight over.
