This challenge is part of Fortnite Chapter 2 Season 3 Week 1 Challenges. You'll have to enter Catty Corner Vault. As in the previous season, some places are guarded by henchmen and bosses, carrying a card allowing access to a vault. This is the case of Catty Corner, a place protected by Kit and his shotgun.
Map
To open the armored door, you're going to have to find and eliminate Kit, then steal his card. Once in your possession, the gold card will show you the exact location of the vault. Inside you'll find high quality weapons and equipment.
Note that the vault cannot be opened in Team Rumble. You'll have to complete this challenge in Solos, Duos or Squads!
