Fortnite update today (17 September): What changes in the v42.20 patch notes?

If you've seen any recent Fortnite news online, then you know that today's the day that the Kingdom Hearts collaboration lands in the game.

Epic Games hasn't confirmed exactly what is coming in this collaboration, but based on the teaser trailers we've seen so far, we have a pretty good idea.

The characters set to get skins are Sora, Riku, Kairi and Roxas, with a collection of Kingdom Hearts cosmetics, Emotes and more set to join the game alongside them.

Additionally, there are a number of further collaborations set to be added to the game's files during this update, although it is not confirmed whether or not these will be released today or in the next week.
