A very special limited time event is coming to Fortnite tomorrow thanks to an unprecedented team-up between Epic Games and Marvel.

The Infinity Gauntlet Limited Time Mashup mode brings Thanos and the Infinity Gauntlet into the game itself. That’s right, the big bad Mad Titan from Avengers: Infinity War will be playable in Fortnite.

In the limited time mode, the game plays out mostly as it normally would, but there’s one big catch, according to Entertainment Weekly. The Infinity Gauntlet will appear on the map, equipped with all six Infinity Stones. Whoever picks up the Gauntlet will transform into Thanos himself and be able to wield all of the glove’s powers.

The team-up came to fruition because Infinity War directors Joe and Anthony Russo are big Fortnite fans, according to EW.

“Over the past few months, while we were editing Infinity War, we’d take breaks to hop on and get in a few games,” Joe Russo said to EW. “And then we started thinking, how cool would it be to have some kind of Avengers–Fortnite mashup? So we stalked [Donald Mustard, creative director at Epic Games].”

Avengers: Infinity War recently broke the record for the biggest weekend opening of all time, and it eclipsed the $1 billion mark at the box office in a record 11 days. This truly is a team-up of epic proportions that even the Avengers might be jealous of.

“Out of the blue, I get this call from Joe,” Mustard said.” And after a bit of geeking out over each other’s work, we start brainstorming these crazy ideas. It was really important that whatever we did, it had to be super authentic to both Fortnite and the Avengers: Infinity War, and something that fans of both would be excited about. About an hour later, we had the bones of this awesome idea for a limited time gameplay mode, and almost immediately our team got started.”

The limited time mode will be available starting on May 8 across all platforms.
