Marvel's What If...?: The Video Game

Marvel's What If...?: The Video Game (or simply What If...?: The Video Game or What If...?) is a superhero video game based off of the comic series of the same name. The game is developed by Crystal Dynamics and published by Square Enix for Xbox Series X/S and PlayStation 5. The game entirely uses cel-shading animation.

Synopsis
Uatu the Watcher tells stories of various ways the Marvel universe could have split from prime.

Gameplay
Similar to the 2020 Avengers video game, Marvel's What If...?: The Video Game is a third-person action-adventure video game which combines an original, cinematic story with single-player gameplay. The game features a unique combat system chaining attacks, dodges, abilities, skills and elements to succeed a combat phase. Also similar to Until Dawn, the game features a "butterfly effect system" in which players must make choices which may change the story.
