"Spider-Men" is an unmarked sequel to Spider-Man: Shattered DimensionsOn the one hand its a spiritual successor, since both stories involve multiple versions of Spider-Man teaming up. And on the other hand, it's a literal sequel. Over the course of "Dimensions", Mysterio was putting together data on the Tablet, getting a lot of irreplicable data on dimensional physics. Using this, he went on to become Ultimate Mysterio, setting up the entire plot.

Miles: With great power comes great responsibility?
Peter: You already know that one?
Peter: Well, that's all I got.
