The week 4 challenges for Season 7 of Fortnite are now live, and one of the free challenges requires players to launch three fireworks - which will require some expert map knowledge.
Although this challenge is pretty self-explanatory, there appears to be very limited firework locations on the whole map, meaning you have to know some specific spots.
Thankfully, if you're not a map expert, we have all the locations marked on the map for you.
Once you are here, simply approach the Firework and interact by holding X on Xbox or Square on PS4, or whatever you interaction keybind is on PC.
This will set the firework alight and send it soaring into the sky - presumably Fortnite's own New Year celebration.
For locations of the other challenges for week 4, check out our full guide here, as well as an in-depth guide for the 'eliminate opponents at Expidition Outposts' challenge here.
There is also a fresh challenge for the 14 Days of Fortnite event, tasking you with dancing in front of nine different holiday trees - check out our full guide here.
