When players logged in to Fortnite, they were met with only one competitive game mode available to them. By joining the Showtime mode at 19:00 GMT, players would see a large concert stage featuring DJ Marshmello's avatar and trademark turntables.
As the music played, Marshmello himself was being broadcast to players, urging them to make their avatars dance along to the music.
The show itself was around 10 minutes in duration and filled with interactive moments, with players being launched into the air during Fly and bouncing beach balls during Happier.
The set, which has been viewed over 11 million times, can be seen on Marshmello's YouTube channel.
