Fortnite's weekly challenges are set to refresh on October 11 but, ahead of that, leaks have indicated what players will need to do to grab this week's Battle Stars. Fortnite Intel reports that there will be three challenges in the free section and four in the paid Battle Pass section, as is standard. And it seems developer Epic Games is leaning into the Halloween angle for a couple of them--although not as much as with the new Skull Trooper challenges.

For Week 3, along with asking players to revive five people in different matches and embarking on a multi-stage quest started by opening a chest in Lonely Lodge, you'll need to ring the doorbell of a house with an opponent inside five times, likely as a nod to trick or treating. Currently the game only allows you to interact with doors by opening and closing them, so it's likely a new animation or interaction of some sort will be rolled out when the challenges go live.
