This challenge is part of the TNTina’s Trial Challenges, the second agent that Fortnite's Chapter 2 Season 2 focuses on. You'll have to destroy a total of ten structures using propane tanks. A challenge perfectly adapted to the explosion enthusiast that is TNTina. The propane tanks were relatively unnoticed during this new season's deployment, so here's where you can find plenty of them.
Map
It's on the oil platform — the historical headquarter of TNTina — that you'll find a very large number of propane tanks. You can find these tanks in other places on the map, but fewer. We recommend this small hiding place, behind a ventilation duct at the south end of the platform:
In this small reserve are several bottles: enough to complete the challenge in only one game!
How do you blow up a tank?
Just like healing items, propane tanks can be thrown over long distances. Approach them and press 'F' to carry them over your shoulders. You can move and throw the bottle whenever you want.
