Dotemu has released a teaser image for Marvel Cosmic Invasion's next downloadable content pack, The Siege of Castle Doom, confirming the DLC is scheduled to arrive in Fall 2026.
The short visual drop points directly to Victor Von Doom as the focal antagonist and signals a thematic shift toward the classic Doctor Doom mythos.
The teaser itself is light on specifics, but Dotemu's announcement makes two clear promises: the expansion will introduce a new game mode centered on Doom and add two bonus playable characters to the roster.
In clear, journalistic terms, Dotemu has said the DLC will include a Doom-focused game mode and two additional playable characters, though the studio has not yet revealed character identities or detailed mechanics.
The Siege of Castle Doom will be Marvel Cosmic Invasion's second post-launch DLC pack.
Earlier this year, Cyclops and The Thing were added to the game's playable lineup in a May update, marking the first wave of character expansions for the title.
That prior DLC demonstrated Dotemu's approach to periodic roster updates and curated seasonal content.
Dotemu is a French developer and publisher with an established track record for revitalizing and publishing retro-styled and licensed titles across modern platforms.
The studio has released multiple high-profile games on Nintendo Switch and the Switch eShop, including Streets of Rage 4 and Teenage Mutant Ninja Turtles: Shredder's Revenge, giving Nintendo hardware owners reason to monitor Marvel Cosmic Invasion's future platform announcements closely.
Official details on pricing, precise release date, supported platforms, and the identities of the two new playable characters are not yet available.
Dotemu's teaser image is the only formal communication so far; fans and industry observers can expect further announcements as Fall 2026 approaches.
For now, The Siege of Castle Doom joins Dotemu's growing list of post-launch content strategies that focus on character-driven updates and themed game modes.
We'll continue to track official Dotemu channels and the game's storefront listings, including eShop entries and publisher updates, for confirmed platform and release information.
