Something big is happening this Saturday in Fortnite, and it's only happening once according to Epic Games. As part of the updates feed in the Fortnite client, the message depicted above was posted early this morning. 

You'll need to be in a match by 10:30 am PT (1:30 pm ET / 7:30 pm CET) this Saturday, June 29 to see what happens, and while the message feigns ignorance, we're betting it has something to do with the massive rocket tucked away in the skull-shaped enemy base on the western shore of the map.
