One of the new things introduced in Fortnite Chapter 2 Season 2 is about mailboxes. Each side of the Agency, Ghost and Shadow, has their own mailboxes, and you'll need to know where they need to complete missions like the final challenge to get a new style for Brutus. You'll have to steal secret blueprints, then deliver them to Ghost or Shadow, depending on which skin you want.
We're not sure if Mailboxes will be needed for anything else, but it will definitely be worth following them all in the game. We'll update this guide as we discover more Mailboxes, and they'll be added. à la carte below, as well as individual screens of each mailbox slot to make them even easier to find by the map in the upper corner of the screenshots.
The map above shows currently known mailbox locations, with the white pins indicating Ghost locations and black pins indicating Shadow locations. Below you'll find screenshots of each mailbox and its location, if you need more help finding them in-game.
