This challenge is part of Fortnite Season 4 Week 4 Challenges and you'll have to deal 10,000 damage with a Gatherer's remains. This is the big challenge of the week, which rewards you 50,000 EXP(instead of 25,000).
This is a rather tedious challenge since Gatherers sent by Galactus appear randomly in rare places on Apollo Island. The most delicate part of all this will be to find a Gorger, and the Gatherers that gravitate around it.
Gorger spawns don't appear on the mini-map using icons, so you'll have to do your own research. To do so, nothing better than Choppas! These helicopters can carry an entire squad and will give you a panoramic view of Apollo Island — ideal to spot the Gorgers from very far away or to survey the island quickly.
Some helicopter locations
Once in the air, you'll be able to spot the large metal sarcophagi in Galactus colors relatively easily. What you'll be interested in for this challenge will be the Gatherers generated by them. The small metal octopuses are fragile and clumsy, and can become weapons once neutralized.
Once shot, Gatherers crash to the ground and you then have a handful of seconds to pick them up and use them as a weapon. The countdown to self-destruction is fairly short, so it's recommended that you destroy them at close range to give you time to collect the debris. Now all you have to do is damage with your Asgard weapon!
Note that the challenge doesn't stipulate on whom the damage must be inflicted. You can absolutely shoot down Galactus drones in a loop to complete the challenge without scaring yourself.
