Marvel Cosmic Invasion’s second paid DLC has finally been revealed, and in keeping with the march to Avengers: Doomsday, it’s Doctor Doom-themed. The Siege of Castle Doom is out this Fall on all platforms and adds two new characters and a new mode.

Further details will be revealed later, but fingers crossed that this new mode is a roguelite twist of sorts, perhaps battling through the various sections of the castle before a boss fight against Doom. As for which two characters could be added, there are a wide number of options, including Mister Fantastic and Namor. Tribute Games could throw in a curveball, though, so stay tuned for updates.

Available for Xbox Series X/S, PS5, PC, Nintendo Switch, Nintendo Switch 2, Xbox One, and PS4, Marvel Cosmic Invasion launched last December to positive critical acclaim. You can check out our review for more details, where we praised the line-up and its attention to detail alongside the combat mechanics.

Tribute Games’ first DLC arrived last May and added two new characters, Cyclops and The Thing, bringing the total roster to 17. It’s unknown whether Dotemu has more content planned after The Siege of Castle Doom, but it could very well cross over with Marvel Tōkon: Fighting Souls, if ArcSys has its way.
