Dotemu and Tribute Games will expand their retro-styled beat-’em-up Marvel Cosmic Invasion with a DLC pack called Siege of Castle Doom, scheduled to launch for PlayStation on 10 November 2026. The studio revealed the date and new features in a trailer published alongside the announcement.
What the DLC adds
The headline addition is a new roguelike mode that places players inside Castle Doomstadt. According to the trailer, runs through the castle will present a randomized assortment of rooms and challenges, with branching pathways that lead to different rewards — a structure the announcement likens to the progression model popularised by Hades.
As players advance during a run they can improve their hero with stat boosts, new equipment and modifiers. The DLC also introduces two new playable characters: Doctor Doom and Invisible Woman, expanding the roster available to players who own the base game.
- DLC title: Siege of Castle Doom
- Platforms announced: PlayStation 5 and PlayStation 4
- Release date: 10 November 2026
- Major features: roguelike mode, randomized Castle Doomstadt runs, new equipment and modifiers, playable Doctor Doom and Invisible Woman
Release details and context
Dotemu and Tribute Games presented the details in a new trailer and accompanying materials. The roguelike addition is positioned as a way to increase replay value by giving players fresh runs with each attempt. The developers showed the mode’s random rooms, multiple pathways and incremental upgrades as the core loop players will encounter inside Castle Doomstadt.
The announcement frames the new mode as an optional expansion of the main game's beat-’em-up systems rather than a replacement for its core experience. The trailer’s description referenced Hades-style progression when explaining the branching reward paths players may find during runs.

The trailer and announcement did not include pricing, regional storefront details or whether the DLC will appear on other platforms at launch. Players in the Philippines who own Marvel Cosmic Invasion on PlayStation should find the update available on the listed date through the usual PlayStation channels if Dotemu and Tribute Games proceed as announced.
Siege of Castle Doom also brings the two named characters—Doctor Doom and Invisible Woman—into the playable roster, which will affect team composition and character choices in both the base game and new roguelike runs.
Dotemu and Tribute Games released the information together with the trailer; the presentation linked to a PlayStation blog and video material used to demonstrate the DLC’s new systems and Castle Doomstadt’s structure.
