Nathan Drake, the protagonist of the Uncharted franchise, is on his way to Fortnite. Epic Games has yet to make a formal announcement about the crossover, but an unlisted video on the battle royale's official YouTube channel has all of the pertinent information. Nathan Drake and Chloe Frazer clothing will arrive in Fortnite's Item Shop on February 17th, one day before the Uncharted film releases in US theaters.
You can play as either the film versions of those characters or their Uncharted 4: A Thief's End equivalents using those skins. For those keeping count, this means Tom Holland will feature in Fortnite for the second time, after the addition of skins from Spider-Man: No Way Home last year.
