MARVEL Cosmic Invasion: The Siege of Castle Doom Gets Release Date And Two New Playable Characters

With New York Comic-Con starting today, Dotemu announced that the next batch of premium DLC for MARVEL Cosmic Invasion, titled The Siege of Castle Doom, will launch on November 10th for consoles and PC. 

Doctor Doom and The Invisible Woman are the new playable fighters, along with a Doctor Doom-themed game mode, which will be revealed later. The exciting reveal trailer showcases this powerful duo in all their glory and sets the stage for an epic next few months, with Avengers Doomsday arriving in theaters on December 18th.

Marvel Cosmic Invasion has already gained over 1.5 million players since launching on December 1st, 2025. The previous DLC dropped back in May and featured Cyclops and The Thing. While there are no pricing details yet, I’m guessing it may fall around $3.99 like the last DLC. Stay tuned for details, and our thoughts on the new characters in the weeks ahead.
