This challenge is part of Fortnite Season 3 Week 10 Challenges and you'll have to destroy a total of seven containers at Dirty Docks. If you have explored the island regularly throughout the season, the location should be clearly marked on your map. If not, here's where you'll have to go.
Map
The containers are these large metal boxes in various colors. You can find a good quantity of them between the cranes and the first sheds in the area. With their 1,200 HP, these items are extremely sturdy and it will take you a while to break seven of them.
Shortly after the release of this challenge, many players will be rushing to Dirty Docks in the hope of completing their challenges. If you feel that this spawn is becoming too dangerous to quietly farmer the containers, fall back to the Team Rumble mode.
