It has been exactly one year since video game developer Epic Games launched the massively popular "Battle Royale" mode of "Fortnite," the company's billion-dollar online multi-player survivor game. 

After Epic Games debuted the "Battle Royale" version of "Fortnite" on September 26, 2017, the game's popularity surged to the point where it now has over 125 million players around the world. In addition to celebrating the one-year anniversary of battle royales in "Fortnite" on Wednesday, Sony also announced that it will enable cross-play for the game on its PlayStation 4 consoles (which means that PS4 players will be able to recover previous "Fortnite" games and in-game purchases from other consoles, like Xbox and Nintendo Switch).
