In Fortnite (PC, Ps4, Xbox One, iOS) you can earn a bonus tier for the Battle Pass again in week 4. The star is once again hidden in a blockbuster loading screen.
Those who are particularly diligent and complete all challenges of a week will be rewarded with a loading screen that may appear unremarkable at first glance and only shows scenes from the game. In fact, there are hidden secret locations of Battle Stars in the images.
What do these bonus tiers bring? These Battle Stars grant you a complete level in the Battle Pass, so you should always collect them as soon as you have completed all weekly challenges. Even in week 4, a secret Battle Star is hidden in the unlockable loading screen:

The image features the main villain Omega commanding his metal army and rallying his troops for an attack (or whatever supervillains do). The Battle Pass can be seen at the top center.
But where is the base with the Battle Star? With the last update, various bases were added to the game – for both superheroes and the dark side of Fortnite’s power. The relevant base is located under a rocket silo near Snobby Shores:

The hideout is a spacious area, including a pool for relaxation and a sleeping area. The Battle Star is located on the upper balustrade.
