The rocket - which can be found in the villain lair - will seemingly launch when the timer hits zero, which is at 6.30pm United Kingdom time on June 30.
This 50v50 LTM will also utilize the same storm patterns as Fortnite Battle Royale's 50v50 version 2, where the final storm circle is visible at the start of the match. It was a good idea in theory, tweaking the usual battle royale formula by limiting the shrinking map; a countdown begins after the final circle closes and whichever team had the most surviving members at the end was the victor (yes, that did mean you could tie for first place).
Likewise, unlockable loading screens show the mysterious Visitor character preparing to launch a strike.
An exact date or time of when players can expect the Playground LTM to become available hasn't been announced. Epic Games is keeping the community informed with regular tweets, but the team hasn't really gone into any specifics. The other team has to take down the Leviathan before it's too late. We want to give you a heads up on the exact ending time. It looks like that rocket that can be found in the evil lair near Snobby Shores is about to launch in a real-time, one-time-only event that you'll need to make sure you're around in-game to see. Season 5 will begin on July 12th at 4 AM EDT (08:00 GMT). While the usual servers were back up and running within a few hours, Playground mode has yet to be restored. We are holding the release until next week to continue hammering away this weekend.
