It's a big week in Fortnite. We're now in Week 9 of Season 8, and the crossover event with Avengers: Endgame has begun, giving players the opportunity to wield iconic weapons against Thanos and his Chitauri army. On top of that, there's a new batch of regular weekly challenges, which you'll want to complete if you're hoping to unlock all the cosmetics for this season.

As always, there are two sets of challenges. The free selection is available to all players, while the Battle Pass challenges are exclusively for those that have spent V-Bucks on a premium Battle Pass. You should know the drill by now: Complete challenges to unlock Battle Stars, which will in turn level up your pass and give you cosmetics to customize your character with.

This week, in the free section, players will need to complete a multi-stage challenge that involves landing in multiple locations, starting with Loot Lake. On top of that, they'll need to search seven chests at either Polar Peak or Lonely Lodge, and ride three Volcano Vents without ever landing.

For those with a paid Battle Pass, challenges involve dancing between specific landmarks, doing damage to enemies from below them, reviving a teammate using a Reboot Van, and taking out five enemies in different matches. You can see the complete list of challenges below.
