Doctor Doom Headlines “Marvel Cosmic Invasion” with “Siege of Doom Castle” DLC This Spring “Marvel Cosmic Invasion,” the cooperative dual-player fighting game nominated for a D.I.C.E. Award, is set to release its premium downloadable content, “The Siege of Doom Castle,” in Spring Brazilian Season 2026 for PC and consoles. This expansion prominently features the infamous Doctor Doom as the protagonist in an entirely new game mode. The DLC will also introduce two playable characters previously unseen in the game, which celebrates classic Golden Age stories and Marvel Entertainment’s legacy. “The Siege of Doom Castle” will launch in Spring Brazilian Season 2026 on PC, Nintendo Switch, PlayStation 4 and 5, and Xbox Series X/S. The game’s roster currently includes 17 playable superheroes: Cyclops, The Thing, Captain America, She-Hulk, Rocket Raccoon, Wolverine, Spider-Man, Storm, Phyla-Vell, Venom, Nova, Black Panther, Beta Ray Bill, Cosmic Ghost Rider, and Silver Surfer. Players can also choose to play as Phoenix or Iron Man.

“Marvel Cosmic Invasion” was released in December 2025, with its first DLC, featuring The Thing and Cyclops, arriving in May 2026. A teaser for the Doctor Doom game mode has been shared by the developers on social media. The game offers a wide array of abilities, styles, and partnerships that players can freely combine as they unlock stellar superpowers and traverse the galaxy. Doctor Doom’s expanded role in “Marvel Cosmic Invasion” follows his significant presence in Marvel Comics last year and his upcoming appearance in an Avengers film scheduled for December 2026. He also debuts this month in “Marvel Tokon: Fighting Souls.” The paid DLC, “The Siege of Castle Doom” (DLC 2), will introduce two new playable characters, whose identities have not yet been revealed. This character pack follows a summer release that added Cyclops and The Thing to the roster, alongside Spider-Man, Wolverine, Phyla-Vell, and Beta Ray Bill. This update followed the game’s initial DLC release in late 2025, which featured a Cyclops character pack.

On OpenCritic, “Marvel Cosmic Invasion” holds an 84 score. Critics recommend the game, describing it as simple, easy to pick up, enjoyable to replay, and ideally played cooperatively. The “Marvel Tokon: Fighting Souls” DLC is expected on Nintendo Switch, Switch 2, PlayStation 5, Windows PC, and Xbox Series X, with no specific release date or price announced as of writing. Currently, there are no further updates or new information to report regarding “Marvel Cosmic Invasion” or the “Siege of Doom Castle” DLC beyond what has already been announced. About Dotemu
