This challenge is part of the Brutus' Briefing, the first agent on which Fortnite's Chapter 2 Season 2 focuses. You'll have to hide in secret passages in three different games. Note that you can use the same secret passage in all three games to complete the challenge. During Season 2, secret passages actually indicate the air ducts of the different Phantom and Shadow bases.
Map
The map above shows you some of the secret passages to go through. Note that there are some elsewhere on the map, but for this challenge you will only need to take them in three different matches.
To enter a secret passage, you have to be crouched down. Metal doors open and close with 'E'.
Secret passages are a good way to escape from pursuers or to infiltrate the heart of a base. They link rooms together and will allow you to quickly find great-quality equipment.
