They have effectively turned Miles into the MCU Peter.
He's gifted a Spider-Man suit by his mentor in Miles Morales. He's reluctant to let Peter know what's going on during the game with Roxxon and the Tinkerer. He tells him it's all good. He thinks he's got it all under control because he wants to prove that he's Spider-Man.
He has Ganke, his own Asian best friend, like Peter has Ned Leeds. They make a suit together similar to the scene in Homecoming when they're in DC and they hack Peter's suit and remove the "baby monitor protocol." This is his homemade suit that he has to wear at the end of the game to overcome the Tinkerer like Peter has to wear his homemade suit at the end of Homecoming to overcome the Vulture.
There's a specific scene in this trailer that demonstrates this further. The New York Water Ride tour boat gets damaged and Pete tells him to help. Did this happen with the Staten Island ferry in Homecoming when Peter crashes the Vulture's weapons deal. One of the Chitauri weapons ends up cutting the ferry in half and Peter has to spring into action.
He almost fixes it but he needs
@Ironman to show up with the little repulsor thrusters to save the ferry.
