This challenge is part of the Brutus' Briefing challenge, the first ever agent Fortnite Chapter 2 Season 2 focuses on. You'll have to disguise yourself as a henchman using telephone booths in three different games. These booths can be found in various locations on the map, which are obviously close to new landmarks — which are full of bad guys and henchmen!
Map
The Grotto
Aim for the entrances to the Grotto, which are close to the sea. In the basement, you'll find a red cabin, against a small grey building.
The Agency
Disguising yourself as is handy for infiltrating secret bases and avoiding being targeted by automatic turrets.
Please note that henchmen and booths aren't present at the Team Rumble. Play Solos or Duos to complete this challenge!
