Marvel Cosmic Invasion

Tribute Games’ Marvel Cosmic Invasion still lacks a release date, but the next best thing is available: A free demo, just in time for this month’s Steam Next Fest. Check out the trailer below to see it in action.

The demo includes two levels – New York City and S.H.I.E.L.D.’s Helicarrier – and nine playable characters, such as She-Hulk, Wolverine, Storm, Nova, Venom, Spider-Man, Captain America, Rocket Raccoon, and more. Unfortunately, the recently revealed Silver Surfer, Beta Ray Bill, Black Panther and Cosmic Ghost Rider aren’t included.

It also offers support for couch and online co-op alongside the Steam Deck, so you can take it on the go. Marvel Cosmic Invasion launches later this year for Xbox One, PS4, Xbox Series X/S, PS5, PC, and Nintendo Switch. The story sees Earth’s mightiest heroes (and anti-heroes) teaming up to battle the threat of Annihilus in side-scrolling beat ’em up scenarios.

The full game promises 15 playable heroes and the Cosmic Swap mechanic, allowing one player to choose two and swap between them at any time.
