Fortnite's Season 4 is coming to an end this week, and that means you better act fast if you want to earn the remaining Battle Pass rewards. The final seven Week 10 challenges were rolled out for players on all platforms last week, and you’ll have until July 12 before they, along with all other Season 4 challenges, disappear.

There are a couple tricky tasks in this week's set of challenges, one of which simply asks players to search between movie titles. For that, you'll have to head northeast of Junk Junction to a cluster of buildings (including a movie studio). That's where you'll find the Battle Star, and you can see detailed directions for finding it in the video above. There's another challenge in the area that asks you to search seven chests in Junk Junction. You don't need to complete it in a single match, so you can repeatedly drop there at the start of a round and open chests until you reach seven. Another challenge has you search a chest, Ammo Box, and Supply Drop.
