The Fortnite World Cup was first announced back in June of 2018, but there hasn't been much news about it since, with Epic Games' attention firmly on the Summer and Fall Skirmishes.
With a total of $100,000,000 in prize pools pledged by Epic Games (Around $18 million of which has already been handed out), there is a lot to play for, and anyone can play.
Epic has confirmed that they will not be selling teams or franchises, or allowing third party tournament organizers to do so either, as they want the game to be inclusive for all players, not just those on a pro team.
But, you will still need to be good enough to make it in, and that's where the qualifiers for the World Cup come in.
Initially, Epic stated that Fortnite World Cup qualifiers would begin in Fall 2018, but that has yet to happen, and the Fortnite website has now been updated to announce a delay to the qualifiers.
Qualifiers for the Fortnite World Cup will now begin in 2019. No exact date or season is given, but it is likely to be early 2019, as the World Cup proper is set for late 2019.
The esports page on the Fortnite website was updated to release details of the new in-game tournaments mode, which looks like it will be the best practice for the World Cup.
Currently, these tournament modes are mainly Solo and Duo, which is interesting given that Epic also stated that "Fortnite World Cup play will focus on Solos and Duos."
Perhaps this new tournament mode in-game will perform a similar function to the 'Solo Showdown LTM', which essentially acted as a qualifier for the Skirmish events.
