The DLC takes players into a fortress constructed by Victor von Doom, where they must overcome traps, powerful enemies, and increasingly difficult encounters before stopping his dangerous plans.

The Siege of Castle Doom DLC Release Date and Platforms

H2 Interactive has confirmed that The Siege of Castle Doom DLC will officially launch on November 11. The announced platforms are PlayStation 4, PlayStation 5, Nintendo Switch, and Nintendo Switch 2.

The publisher has also released an overview video offering a closer look at the expansion’s gameplay features and setting. While the announcement concerns the Korean version of MARVEL Cosmic Invasion, players can look forward to a new mode that puts greater emphasis on adapting to challenges across repeated attempts.

Further information about regional availability and any additional release details can be found through the game’s official website.

New Run-Based Action Mode and 12 Perks

One of the DLC’s main additions is a run-based action mode in which players progress through challenges attempt by attempt. During these runs, players collect Battery Cells and complete objectives to acquire upgrades from a pool of 12 different perks.

These perks can improve defensive capabilities, increase attack power, or enhance tactical abilities, allowing players to adjust their approach as the difficulty rises.

Players must also choose their routes and buffs while navigating interconnected paths throughout Castle Doom. Traps, Doom Bots, and bosses from the base game stand in their way, making each run a test of combat skills and decision-making.

The mode’s central challenge is the Siege Gauge. As it fills, enemies become stronger. If the gauge reaches its maximum before players face Doctor Doom in the final battle, the attempt immediately fails. Reaching the final encounter in time is therefore essential to completing the siege.

Stop Doctor Doom Before the Cosmic Inductor Activates

The DLC’s story revolves around a dangerous weapon known as the Cosmic Inductor. Although it was designed to stop Annihilus, the device contains a fatal flaw that threatens to plunge the entire universe into an apocalypse.

Players must breach Castle Doom’s defenses and stop Victor von Doom before the weapon activates.

A stabilizing device developed by Reed Richards of the Fantastic Four plays a crucial role in the mission. The device charges as players survive combat, becoming a key part of their efforts to thwart Doom’s plans.

This combination of a time-sensitive objective, escalating enemy difficulty, and route selection gives the expansion a clear central challenge beyond simply defeating waves of enemies.

Susan Storm and Doctor Doom Join the Playable Roster

The Siege of Castle Doom introduces two new playable characters: Susan Storm of the Fantastic Four and Doctor Doom.

Completing challenges also provides permanent progression rewards, including new equipment and events that become available in Reed’s Lab. Players can unlock modifiers that increase difficulty in exchange for greater rewards on future attempts.

However, failure carries a cost: unsuccessful challenges apply a debuff to the player’s character, adding another consideration to each run.

Defeating Doctor Doom also unlocks new color palettes for every playable superhero, giving players additional customization options as they continue playing.

The expansion further adds an original soundtrack composed by Tee Lopes, bringing new music to the Castle Doom experience.
