For one of Thor’s Awakening Challenges in Fortnite Chapter 2 Season 4, you will need to get to the Bifrost marks. These are leftover from all the Marvel characters appear in the game and are burned into the ground, making them easy to spot. For anyone not up to date on Thor lore, the Bifrost is the way that Asgardians move between the realms, and it has featured many times in the Marvel Cinematic Universe and the comic book.
You can find the Bifrost marks directly south from The Authority, in the hills between Weeping Woods and Lazy Lake. They are deeply burned into the ground, and still have an orange glow to them. It is very easy to drop straight onto them.
You don’t need to do anything special when you get there; just arriving at them is enough to complete this part of Thor’s Awakening, and you can then proceed through the rest of the match as normal.
Fortnite Chapter 2 Season 4 has introduced lots of new Marvel characters to the game, and you can get them all by leveling up the Battle Pass. As well as the skins, you will also be able to access special Awakening Challenges that will unlock a special emote that can change the skin. Jennifer Walters changes in She-Hulk, Tony Stark become Iron Man, and so on.
It is a really neat touch, and a great way to start out the new season.
