Here’s the location where you’ll be able to find the Fortnite Season X, Week 2 hidden secret Battle Star for the shootout at sundown mission challenges.
Epic Games confirmed during Season X, week 1 that there was an issue with the hidden Battle Stars for both week 1 and week 2. According to Epic, the Battle Stars were “extra hidden” and players weren’t able to collect them even if they were in the correct location. The fix for this bug/issue has been added in today’s v10.10 patch update, and players will now be able to collect the secret battle stars.
Players are rewarded with a loading screen upon completing 3 of the shootout at showdown mission challenges, which were released on August 8th and will be available until tomorrow, August 15th. Here’s a look at the loading screen that provides the location of the Battle Star:
