"Fortnite Battle Royale" has also become a cultural online phenomenon, with several celebrities reporting they play the game, and athletes using "Fortnite" emotes as victory celebrations. A notable streaming event in March 2018, with streamer Ninja playing "Fortnite Battle Royale" alongside Drake, Travis Scott, Kim DotCom, and Pittsburgh Steelers wide receiver JuJu Smith-Schuster, broke viewership records for Twitch to date, and led to Epic arranging a "Fortnite Battle Royale" pro–am with 50 pairs of streamers and professional players matched with celebrities at the Electronic Entertainment Expo 2018 in June 2018. Epic Games is working to develop organized eSports competitions around "Fortnite Battle Royale", including a "Fortnite" World Cup tournament in 2019.
Battle royale game
While there have been several successful battle royale games, the genre has seen a number of games have bursts of popularity before their concurrent player count drops. In contrast to other multiplayer-only games, the large number of players typically involved in battle royale games generally require a large enough concurrent player base for matchmaking in a reasonable amount of time. "The Culling", by Xaviant Studios, was released in early access in 2016, and was designed to be a streaming-friendly battle royale mode for 16 players. However, following the release of "Battlegrounds", "The Culling" lost much of its player base, and a few months after releasing the full version of the game, Xaviant announced they were ending further development on it to move onto other projects. "Radical Heights" by Boss Key Productions was launched in April 2018 but within two weeks had lost 80% of its player base. "SOS", a battle royale game released by Outpost Games in December 2017, had its player counts drop into the double-digits by May 2018, leading Outpost to announced the game's closure by November 2018.
