Season 5, with the slogan Worlds Collide, was the fifth season of Fortnite: Battle Royale. It started on July 12th 2018. It was scheduled to end on September 24th 2018 but was extended after Epic Games had extended the season to end with the 1 year anniversary of Fortnite being Free to Play.
The theme revolved around world collision, following the aftermath of Blast Off, which resulted in things being taken from other realities and put into Reality: Zero.
