Fortnite's annual Summer update drops June 25, so soon enough, gamers will have plenty to keep them busy in-game. Epic Games tends to update Fortnite every two weeks. Apart from the days when there's an unexpected inconvenience or an upcoming crossover event, gamers can usually expect downtime to start around 2 AM ET on Tuesdays. Downtime tends to last a couple of hours - however, this depends on the size of the patch, - and then fans can normally jump back into the game between 6 AM and 9 AM.
