Here's a round-up of what happened so far (via the Press Association):
The entire Fortnite map disappeared into a black hole, leaving gamers unable to play as part of a world event to mark the end of the 10th game of the season.
The popular royale fighting game is known for its big showman show events, and developer Epic Games previously confirmed that the event, known as "The End," will take place on October 13.
Those who logged on to Fortnite on Sunday night saw the virtual island where the game was being held, struck by a meteor shower before the whole map seemed to be sucked into a black hole.
Since then, anyone who enters the game has been presented with a live stream of the black hole and no way of playing.
As part of a complete blackout t, Fortnite's official Twitter profile also deleted all of his tweets except a live stream of the black hole. It has been retweeted more than 120,000 times.
The game – which sees up to 100 competitors compete as the last player – is broken into seasons that span several months, with the start of each new season marked by game events.
This latest showman coincides with the end of the 10th season of the game – with many now expecting a major update to the game and its setup on the island before returning for an 11th season, likely to begin in the coming days.
Previous major Fortnite events include meteor shower, rocket launch, and a battle between a giant robot and a monster all over the map earlier this year.
Since its initial release in 2017, Fortnite has become one of the most popular video games in the world.
The free play attracts more than 100 million players and sees its running dance moves, played by a number of athletes during major world events, including the Fifa World 2018 Cup.
