Doctor Doom Returns Ahead of Avengers: Doomsday in New Marvel Release

Marvel Cosmic Invasion developer Tribute Games has revealed its upcoming Siege of Castle Doom DLC, which will focus on Doctor Doom just a few weeks before the character's big-screen appearance in Avengers: Doomsday . Released in 2025, Marvel Cosmic Invasion debuted with a playable cast of 15 heroes. Favorites like Spider-Man, Captain America, and Iron Man were included in the initial roster, alongside some deeper cuts such as Cosmic Ghost Rider and Phyla-Vell. Earlier in 2026, Marvel Cosmic Invasion added Cyclops and the Thing in the game's first batch of DLC.
