There have been many different fan theories going around in the community about the changes that have occurred since the last update.
Reddit user vigilancefoetracer has translated the vibrations felt by console players in Morse Code:
There are four different patterns that are felt by console players and they have been translated to “SOS” “D” “5” and “418”. It seems as though Tilted Towers will be targeted as it is located at D5 on the map!
Some players think that the “418” is a reference to April 2018 and not necessarily the 1st April as suggested in the post. The user has suggested that the SOS is in reference to a meteor that could be coming to Fortnite.
