New heroes and villains are introduced into Marvel’s comic-book continuity almost every week. Iron Man periodically exchanges laser fire with new techno-villains, and different characters suit up as Captain America for a spell, but these story deviations from the core conflicts and characters rarely have lasting impact in the universe. Most of the new characters disappear into Marvel’s expansive archives and are never heard of again. Some of those forgotten heroes find a home in Lego Marvel’s Avengers.
On the surface, this is a video game adaptation of the Marvel Cinematic Universe. The game offers lengthy campaigns that recount all of The Avengers and The Avengers: Age of Ultron. Tucked off to the side are additional levels based on Iron Man 3, Captain America: The First Avenger, Thor: The Dark World, and Captain America: The Winter Soldier.
