Stealthy Stronghold May Be Getting a Big Boss Fight While Epic Games recently brought the Winter update to Fortnite, some leaks are suggesting a big upcoming boss fight in the new Chapter 2 Season 5 location: Stealthy Stronghold. According to data mining from known leaker Fort Tory, the folder for Stealthy Stronghold contains references to a nightmare as well as a file called “S15 Boss.” The Stealthy Stronghold includes several references to the well-known movie monster, Predator. Fortnite Chapter 2 Season 5 is available for free right now on current and next-gen consoles, PC, Mac, and Android. “There are files referencing a possible boss at Stealthy Strongholds. So whoever could this possible boss be? The Predator as some people theorize or someone else?” said Fort Tory on a recent Twitter post. “Stealthy Stronghold is called ‘Nightmare’ in the files and we have an S15Boss/LagerEventData_Nightmare.” Stealthy Stronghold was recently added to the Fortnite map with the release of Chapter 2 Season 5 and it’s an enclosed jungle area with multiple Predator references, including a truck turned generator that fans will be familiar with and a crashed helicopter that’s a dead giveaway.
