Alongside the new Aquaman challenges, there will be the usual weekly challenge you can complete to earn XP. For this challenge, you’ll need to visit Agent Meowscles kitty hideout at Catty Corner and open the Vault. The Henchmen from the previous season are still lurking around the map and you’ll find a bunch of them at this new location, so here’s what you need to do to get the keycard and open the Vault.
Fortnite: Chapter 2 Season 3 - How to enter the Catty Corner Vault
Catty Corner can be found in the lower right corner of the map near Lazy Lake. There’s a giant pawprint on the wall outside, so it’s difficult to miss.
Once inside, you’re looking for a Henchman Boss called Kit, a wee robot Meowscles wannabe. You’ll need to defeat him and then he’ll drop the keycard you’ll need for the Vault. You’ll be guided to the Vault which is underneath one of the yellow containers, so interact with the computer nearby to open it and finish the challenge. You’ll get a tasty 35,000 XP for this challenge, so make sure you have a few weapons and healing items to hand before you go in. If you missed the beginning of Season 3, you can check out all the map changes here, as well as all the Aquaman challenges.
