Overview
- Tribute Games and Dotemu announced the Siege of Castle Doom DLC on Monday, Aug. 17, 2026, confirming a Doctor Doom‑centred game mode and two additional playable characters.
- Publishers say the expansion will arrive on PC and major consoles in fall 2026 but have not revealed a specific release date or the DLC's price.
- The companies describe the add‑on as premium paid DLC and have not stated whether Doctor Doom himself will be a playable character.
- This is the game's second paid expansion after a earlier character pack added Cyclops and The Thing, and it follows strong critical reception and multi‑million player interest in the base brawler.
- Coverage frames the timing as part of a broader Doctor Doom spotlight across Marvel games and the MCU, a move that could boost player engagement and drive coordinated promotion ahead of the Avengers: Doomsday film.
