Outside the story, the player is able to complete side missions to unlock additional content and collectible items. Miles can freely move around New York City, interacting with characters, undertaking missions, and unlocking new gadgets and suits by progressing through the main story or completing tasks. Gameplay is presented from the third-person perspective with a primary focus on Miles' traversal and combat abilities. The narrative focuses on Miles' struggle to balance the duties of his civilian persona and his role as the second Spider-Man when his new home, Harlem, is threatened by a war between the Roxxon Energy Corporation and a high-tech criminal army called the Underground, led by the mysterious Tinkerer. The game is a spin-off sequel to Marvel's Spider-Man (2018), and the second installment in Insomniac's Spider-Man series.
Based on the Marvel Comics character Miles Morales, it is inspired by both the character's decade-long comic book mythology and the 2018 animated film Spider-Man: Into the Spider-Verse, which helped popularize him. Marvel's Spider-Man: Miles Morales is a 2020 action-adventure video game developed by Insomniac Games and published by Sony Interactive Entertainment.
