It is clearly visible that Fortnite won the world on this day, right exactly before Christmas with the release of the Season 7. With that being said, more news is about to come, together with tricks and tips. One of them is the Season 7 Week 1 Hidden Battlestar.
The hidden Battlestar for the opening week is located in the new and reconstructed area of the map. More precisely, it is found in B8 on the map grid.
Over there, a crashed submarine is quite visible with a bare eye and you cannot miss it. It is found on the top of a mountain. As soon as you complete all of the challenges, make sure you head to B8 and just by gliding you can get on the very top of it. The Battlestar is found on the front of the submarine.
