Fortnite has experimented with a lot of biomes over the years. However, in Fortnite Season 7, the developers found their hands on a low gravity biome.
Although there is only one POI in game currently with the low gravity biome, a few more will be joining in soon.
But once you're at the low gravity biome, where do you find chests? We'll take it one by one.
Low gravity areas in Fortnite
For now, there's only one low gravity area on the Fortnite map. If you haven't already guessed it, I'm talking about Holly Hatchery.
That POI was taken over by the aliens recently, and now they've ended up establishing their own sort of biome in the POI.
Initially it started with the store in the middle of the house, and then the houses followed suit.
You could also experience low gravity on the Mothership, but that isn't on the island technically. Coming back to Holly Hatchery, you'll notice that there is a form of a barrier formed around the houses in the region.
This barrier is where the effect of low gravity can be felt in Fortnite Season 7.
Once you're inside these areas, all you need to do is look around the place for chests and ammo boxes. The big building right in the middle of the POI will always see a chest or two spawn in there.
All you need to do is loot three of those chests and ammo boxes and you'll be done with the Fortnite week 6 challenge.
On the other hand, if you're feeling fiesty enough, all you need to do is toss an Alien Nanite cube in front of any chest or ammo box and then loot them. It'll count towards the challenge, yes, but that's a perfect waste to the very useful Alien Nanite cube.
