The electronic music producer has listed a show on Saturday at Pleasant Park, one of the locations on the Fortnite map.
Pleasant Park is an ideal spot for the concert, given that it’s home to a football ld.
Although Fortnite’s maker Epic Games is yet to confirm the event, players have already reported spotting stage preparations around the area.
According to Marshmello’s web listing, the show will start at 7pm UK time.
Marshmello is no stranger to Fortnite, having played the title’s Battle Royale mode with gaming celebrity Ninja last year and winning a special tournament at the E3 video game conference.
One-off special events have helped contribute to Fortnite’s success, although the concert will be the first the popular survival game has hosted.
They have included zombies for a Halloween-inspired Fortnitemares event, and a fan-made movie screening which used footage shot entirely within the game.
