Alongside a new update, Epic Games has released the next set of weekly challenges in Fortnite: Battle Royale. As is typically the case, there are a total of seven new objectives for Battle Pass owners to complete on PC, PS4, Xbox One, and mobile. One important note to be aware of before diving in is that the new limited-time mode, Sniper Shootout v2, is not granting rewards, XP, or progress at the time of this writing, but Epic is working on the issue.
