It looks like Epic Games and Marvel finally decided to confirm the news that people already knew from dataminers weeks ago, as Avengers content is coming to Fortnite. As part of the celebration of Avengers: Endgame being released this week, Fortnite appears to be getting some cosmetics and other items added to their various modes starting on April 25th. This was teased on Twitter today showing off one of the characters holding Captain America's shield, which we're guessing will be turned into a parachute in the game.

Aside from the fact that we'll probably see the return of the Thanos Infinity Gauntlet mode from last year, and the fact that we'll probably get new skins for characters to wear, there's been no confirmation from the developers as to what they plan to include in Fortnite just yet. We're guessing that will come with the next update, which will probably also include more Season 9 additions being added to the code as they're gearing up for next season. It'll be a long three days until we know what's been added, unless someone wants to datamine the game again.
