Check out the first teaser trailer for Marvel Cosmic Invasion: The Siege of Castle Doom below:
MARVEL Cosmic Invasion is available now for PlayStation 5, Xbox Series X|S, Nintendo Switch, Nintendo Switch 2, and PC via Steam. Final Weapon reviewed the game and gave it a 4/5, stating that it “continues Marvel Games’ effort to experiment with the beloved IP. The use of fan-service and both obscure and iconic characters in the narrative is so well done, the gameplay mechanics are extremely fun to play around with, and the art style is a treat to look at. While there are problems with the game’s difficulty spikes, limited replayability, short runtime, and lacking soundtrack, the strengths of the overall experience far outweigh its weaknesses.”
Lastly, the Steam page of Marvel Cosmic Invasion describes the game:
“The Cosmos Must Fall So That I Might Live!!”
So swears Annihilus, the living death that walks! After an unprecedented attack is launched across the galaxy, all life hangs in the balance.
Nova, Spider-Man, Wolverine, Phyla-Vell, Captain America and many more heroes, both earth-born and cosmic, will join forces in a star-spanning brawling adventure against the deadly Annihilation Wave. From New York City to the depths of the Negative Zone, the future of the Universe will be fought for across the stars in MARVEL Cosmic Invasion!
