Fortnite Battle Pass Level 49 (Jump 31): Investigate an anomaly detected in Catty Corner
Now we're heading for Catty Corner, specifically the military bunker at the foot of the mountain. Head towards the main door to spot the butterfly.
It will lead you inside, and you'll see that a vault door, slightly ajar, blocks your progress. To blow it up, pick up one of the Boom! Barrels found outside.
Throw it against the vault door and then shoot it - from a safe distance! - and wait for the resulting fire to subside. It may take several barrels, depending on your positioning.
Once the vault door is wide enough, simply interact with the anomaly behind it to complete the challenge.
This one unlocks the Jump 31 style for Agent Jones, in which his suit seems to have become an improvised martial arts gi.
