Once again there is a crossover between Fortnite and Marvel, which should revolve around the god of thunder Thor at the beginning of Season 4.
After Deadpool, Aquaman and many more, Thor will be the next Marvel hero around whom an event in Fortnite will be knitted. At the beginning of the 4th season on Friday (August 27th) suggests Epic Games "The omens of war" for that day.
That sounds like a larger in-game event and should obviously only be the first part of the whole. Since the first big appearance of Thanos for the release of Infinity War, the Marvel heroes have been regular guests in the Fortnite universe.
There was a comic in the game after the tweet. This shows Thor in conversation with World Eater Galactus. Some players now suspect that for the start event of the season, the world must be defended against the villain together with Thor. But in the comic from which the picture from the tweet also comes, Thor is the Herald of Galactus, just like the Silver Surfer was.
By the way, the picture of Thor in the tweet shows the appearance of the hero from the comics. It seems Epic Games is not based on the Marvel Cinematic Universe, but the next Thor film Thor: Love & Thunder is not planned until 2022, so she probably didn't want to wait that long.
Season 4 in Fortnite starts on August 27, 2020.
