Tribute Games and Dotemu are lining up a second DLC pack for Marvel Cosmic Invasion, and The Siege of Castle Doom is due in fall 2026. The add-on will introduce a new game mode and two playable characters, while Doctor Doom will be central to the mode's setup.
One important detail is still unanswered: it has not been confirmed whether Doctor Doom himself will be playable. For now, the developers have only said that the mode will revolve around him.
The Siege of Castle Doom will be Marvel Cosmic Invasion's second DLC. Earlier this summer, a character pack added Cyclops and The Thing to the side-scrolling action.
The expansion will launch on Nintendo Switch, Switch 2, PlayStation 5, Windows PC, and Xbox Series X/S. A specific release date and the DLC's price have not been shared yet.
Will Doctor Doom end up being playable in The Siege of Castle Doom, or only shape the new mode?
