With Season 5 of Fortnite: Battle Royale on the horizon, Epic has begun dropping more and more hints that something major is about to happen in the game very soon. Ahead of the new season, which formally kicks off on July 12, players have begun to notice some ominous warning signs around the map, and a new in-game update confirms that some sort of big event will take place tomorrow, June 30. [Update: As teased, Fortnite's rocket has launched, creating a mysterious "rip" in the sky that can be seen over the map.]

In Fortnite's New Updates section, Epic has teased that a launch of some kind is scheduled to happen in the game this Saturday, but you'll need to be in a match at the right time in order to witness it. "Get in-match on Saturday by 10:30 AM PT / 1:30 PM ET / 7:30 PM CET and look to the sky. It only happens once!" the update reads.

Fans have speculated that the recent warning signs that have begun appearing in Battle Royale were tied to some sort of rocket or missile detonation. Earlier this month, players began to notice countdown clocks displayed on screens across the map. Following this week's 4.5 update, players have also begun hearing a siren sounding out near the Evil Lair in Snobby Shores, which just so happens to house a mysterious rocket.

It remains to be seen what effect--if any--this launch will have on the game, although this wouldn't be the first time Epic has ushered in a new season with a world-changing event. Prior to the start of Season 4, a large comet appeared in the sky over the map. The comet hung in the stratosphere for several weeks until it eventually crashed to start Season 4, altering the landscape in the process by transforming Dusty Depot into Dusty Divot.

If the mysterious event isn't enough incentive to hop on Fortnite: Battle Royale tomorrow, Epic is also offering double XP from June 29 to July 2 to help players unlock their remaining Battle Pass rewards.
