In this new storyline, heroes and villains unite in a race across the Marvel Universe to find the Infinity Stones before Thanos and The Black Order use them to unleash cosmic chaos. From Avengers Tower to the X-Mansion and beyond, every stop on the dangerous quest to thwart Thanos results in unexpected collisions of fan-favorite characters and iconic locations.
Get closer to the action by shifting the view to an over-the-shoulder "Heroic Camera" perspective—a series first that offers a more immersive way to play single-player or multiplayer on up to four systems. Play online*, offline via local wireless, or simply pass a Joy-Con controller to a friend, so they can join your team. With another pair of Joy-Con™ controllers (sold separately), four players can team up on one system! The drop-in/drop-out co-op possibilities let players create their own "Ultimate Alliance" at will.
