Update: Aiming at the comet causes a strange sound to occur:

The Tilted Towers destruction theory started out simply with the sighting of a comet in Fortnite’s sky which has grown in size over the past few weeks. This has transformed, however, into something much bigger.

A few days ago, players started spotting small ‘shooting stars’ in the sky as can be seen in the top right of this clip:

As of today, April 18, the date which many expected the comet to hit Tilted Towers, many meteors on a much larger scale have started to appear:

We will keep this post updated with the latest information surrounding the comet and meteors, stay tuned.
