Marvel Cosmic Invasion is set to receive new DLC called “Siege of Castle Doom,” launching on PS5 and PS4 on 10 November 2026. The expansion is described as a doomsday-themed add-on for the game, and outlets say a trailer and new details have been released alongside the announcement.
The DLC’s central addition is a roguelike or roguelite-style game mode connected to the “Castle Doom” premise. Nintendo Life describes the mode as a palace-based challenge where players work through the area and take on Victor, with Doctor Doom and Sue Storm appearing as playable characters. Vice focuses on how the DLC changes gameplay compared with the main campaign, highlighting that new mechanics will distinguish the expansion from standard play.
Across coverage, the shared thread is that “Siege of Castle Doom” expands Marvel Cosmic Invasion with a new mode and gameplay differences, while emphasis varies between release timing, the roguelike structure, and the specific ways mechanics will diverge from the campaign.
