Epic continue to tease players of Fortnite with lightning strikes that destroyed cacti and now a mysterious purple cube has begun travelling across the map. The purpose of the cube is a mystery, but it does have some symbols on the side of it but players have yet to decipher these because as soon as they get close to the cube they get pushed back.

Rumours that Phillip Schofield will be hiding inside the cube along with a mini-game where you have to bounce tennis balls in to a bucket have yet to be substantiated.
UPDATE: Someone manage to get inside the cube and it was empty. We still think Schofield is responsible though.
