Lego Marvel Super Heroes is an action game where about 150 Marvel heroes and villains from various franchises team up to save Earth from a group led by Galactus. The game features a blocky cartoonish visual style reminiscent of LEGO adventures. Players control the good guys as they battle against the bad ones.
The game's world is open, allowing players to explore Manhattan, visit famous Marvel locations like the Marvel HQ, and play through self-standing story mode levels set in Asgard, Bifrost, and Asteroid M. In New York City, players can enter various Marvel-related buildings and hear narrations from Deadpool.
The game starts with Iron Man and Hulk as playable characters, with Spider-Man joining later on. Additional characters are unlocked by progressing through the game or collecting Gold Bricks, which can be found in Manhattan, during story mode levels, or by completing side quests. Other collectibles like Minikits, Deadpool bricks, and tokens offer extra outfits, vehicles, and powers. There are over 150 playable characters, with more than 100 needing to be unlocked, each with their own Super Powers and moves.
The game features voice-acted dialogues from a cast of 27 people. On Xbox One, the game allows for off-TV play using the GamePad, and in two-player mode, players can use the GamePad's display without split-screen issues.
