MARVEL Cosmic Invasion Demo Hits Steam Ahead of Nintendo Switch and Switch 2 Release The highly anticipated beat 'em up, MARVEL Cosmic Invasion, is set to land on the Nintendo Switch and the next-generation Switch 2 later this year.

Developed with fast-paced co-op action in mind, the game lets players step into the shoes of beloved Marvel heroes as they face cosmic threats in a new, original storyline.

In a recent development, a playable demo for MARVEL Cosmic Invasion launched on Steam, offering PC gamers an early opportunity to experience its dynamic combat and diverse character roster prior to its official release on Nintendo platforms. The MARVEL Cosmic Invasion demo grants players access to a selection of iconic heroes.

It provides a preview of the robust beat 'em up mechanics, squad-based powers, and multiplayer features that are set to be a highlight of the full title when it arrives on the Nintendo Switch, Switch 2, and Steam.

This marks one of the first major Marvel co-op gaming experiences to have a simultaneous planned release on both current and next-generation Nintendo hardware, further underscoring the publisher’s commitment to Nintendo platforms. Following the release of the demo, the game generated additional buzz when a community datamine, conducted by users exploring the Steam release, uncovered references suggesting Iron Man and Phoenix will be included as playable characters.

This leak points toward an even more expansive roster than previously revealed.

While developer or publisher statements are yet to officially confirm these details, these findings indicate potential downloadable content (DLC) plans for future roster expansions. MARVEL Cosmic Invasion already boasts a lineup featuring She-Hulk, Rocket Raccoon, Venom, Phyla-Vell, Spider-Man, Storm, Wolverine, Nova, and Captain America.

The datamined roster expansion, if validated in official channels, would add significant star power to the game and elevate fan excitement for the Nintendo Switch, Switch 2, and Steam versions alike. At present, the demo is available exclusively via Steam with no mention of immediate plans for a Nintendo eShop demo release.

The development team has emphasized their intent to keep players informed regarding future content and demo availability on other platforms as development continues and launch dates approach. With its robust character selection and classic brawler mechanics, MARVEL Cosmic Invasion is positioned to become a must-play title for fans of the genre and Marvel enthusiasts when it arrives on Nintendo Switch, Switch 2, and PC later this year.

Stay tuned to official announcements for confirmation on additional characters and DLC plans as launch draws closer.
