The long-rumored Fortnite collab with South Park is now official, as Epic Games dropped a new short film that shows how the boys are going to get sucked into the metaverse. We also got some specifics about what the collab will entail: a new five-player mode for Battle Royale, a free mini-pass through which players can earn South Park cosmetics, and at least five skins in the item shop. Oh, and Wonkeeland on the BR map will become Cartmanland.Using a short film to reveal the collab is something that Fortnite recently also did for its Simpsons-themed season in November--a Fortnite collaboration being something else that The Simpsons did before Butters could. The brief video, which includes a gameplay teaser at the end, shows us that the boys are avid Fortnite players, but Butters never gets to play with them since squads are capped at four players. So he tries to use the Stick of Truth to make them play with him, but it doesn't go quite the way he thought it would.South Park's intrusion into Fortnite will come with several changes for Battle Royale. Wonkeeland is now Cartmanland, there will be a Cheesy Poofs healing item and a Stick of Truth mythic weapon, and for the first time you'll be able to play Fortnite's main mode in a group of five. Beyond that, this collaboration will also include an event pass--something Fortnite used to do regularly until the end of Chapter 5. This pass will be free to everyone, and we don't know anything about what it will include.In the item shop, you'll find skins for Stan, Kyle, Kenny, Cartman, and Butters--all in mech suits, judging by the teaser. There will also be a Towelie sidekick, though we don't know if that will be in the shop or on the event pass.The Fortnite x South Park event runs through February 5.
