In this guide, you will learn about the Bifrost location in Fortnite, which is a week one challenge.
You will first need to go to the location, as shown on the map below.
When you get to the location, you will easily spot the frost marks on the ground, as you can see in the image below.
When you go up there, you will unlock the challenge. Now you have to head back to exit the match and go to the battle pass map challenges; then, you will find that you have to deal the damages to opponents using Mjolnir as thor, as shown in the image below.
To complete it, you will need to go to the team rumble, and you have to emote at the tallest mountain on the map, Catty Corner.
And then, this challenge will be completed.
