About This Content

Welcome to MARVEL Cosmic Invasion - The Siege of Castle Doom, the second expansion of MARVEL Cosmic Invasion, which includes two new playable characters and a new game mode.

Equipped with high-powered tech armor of his own design, along with occult skills and his genius intellect, Doctor Doom is the biggest threat in the universe... and Annihilus definitely won't be up to the challenge.

Cosmic rays have given archeologist and explorer Susan Storm massive light-bending powers and force field manipulation. She now fights for the survival of the galaxy as The Invisible Woman, bringing in never-seen-before abilities to MARVEL Cosmic Invasion.

MARVEL Cosmic Invasion: The Siege of Castle Doom will put the leader of Latveria at the center of its new game mode, set in the nefarious Castle Doomstadt. More details coming soon!
