The new add-on sends players to Latveria for a Doctor Doom mission, with Marvel Cosmic Invasion revealing only a teaser slate and no gameplay footage.
Fall 2026 is the announced window, but the tease offered no exact release date, screenshots, or confirmation of which new characters will join the expansion.
The DLC is positioned around Avengers: Doomsday buzz and marks the game's second expansion, with earlier reports saying it will add a new mode and two bonus playable characters.
Marvel Cosmic Invasion itself is a tag-team beat-'em-up built around the Cosmic Swap system, where heroes battle Annihilus and the Annihilation Wave across the galaxy.
