Epic seems to have made some massive changes to the Fortnite map in the newly launched Season 6, giving everything a midnight feel to it, but those aren’t the only changes the developers are bringing to the game this season.

Alongside the new creepier map, Epic has also made a few big changes to which weapons are in the game, even going so far as to vault some fan favorites like Impulse Grenades, and adding a new item that allows players to turn invisible and phase through solid objects. Not everything about this patch is dark and scary though. Epic has also added pets to the game as loyal companions that will accompany players through each game to balance things out.
