What was the first live in-game event in Fortnite called?

Fortnite’s first live in-game event was called the Rocket Launch. It took place on June 30, 2018, during Season 4, when a rocket launched from the Visitor’s lair near Snobby Shores.

Players gathered in matches to watch the countdown and launch unfold in real time. The rocket flew into the sky, passed through several rifts, and left a large crack across the sky. That visual aftermath helped establish Fortnite’s evolving island story, in which map changes and spectacle became part of each season’s narrative.

The event is sometimes confused with later phenomena such as the Ice Storm, the Volcano Eruption, or the Cube storyline. Those were separate seasonal events. The Rocket Launch was the first major live event synchronized across the game’s servers, and it demonstrated how Fortnite could turn a multiplayer match into a shared story moment.
