The countdown is over, and a mass of Fortnite players had gathered near the rocket to see what was about to happen. It was an interesting scene from the ground; no one was attacking each other, a few people built benches to give other players a better view of the actions, and there was a lot of dancing.

It’s hard to tell exactly what happened and in what order; there was a series of events that we’re still trying to piece together based on replays. But it looked as if the rocket broke apart after launch, and then a portion fell back down, firing a laser at the ground. Another rocket then appeared through a portal that seemed to have been opened by the first rocket, flew around for a bit, before it too disappeared. And then another rocket was appeared from a portal, flew straight up and opened what seems to be some kind of rift in the sky. It was a spectacular series of events.
