Selve afsløringen af Spider-Man: Miles Morales var måske lige præcis lidt mere forvirrende end den burde have været, for for en stund fremgik det ikke helt tydeligt om hvorvidt der var tale om en udvidelse, eller et separat spil. Men nu ved vi at der er tale om et helt separat projekt, men vi ved samtidig også, at det ikke kan kaldes et spil af samme størrelse og kaliber som Spider-Man.
I en opfølgende artikel på PlayStation Blog forklarer instruktør Brian Horton, at det måske kan sammenlignes en del med Uncharted: The Lost Legacy, som jo var et separat spil, men som tilbød en mindre kampagne.
"We know a lot of you want to know how big this game is. Our team at Insomniac has been working incredibly hard to bring you a fantastic Miles Morales adventure since we concluded development on Marvel's Spider-Man. You'll experience a full story arc with Miles, one that's more akin to a game like Uncharted: The Lost Legacy in terms of overall scope. Marvel's Spider-Man: Miles Morales is an important, heartfelt, emotional and essential experience to expanding the Marvel's Spider-Man universe. And we hope it will be for you as well."
Som WCCFTech noterer, så er kampagnen i Uncharted: The Lost Legacy mellem 5 og 10 timer lang.
Desuden giver Horton os også en lille opsummering af plottet:
"Let's set the scene for the game a little more. It's now wintertime, about a year after the events of the first game. Marvel's New York is covered in snow, and just before Christmas break, and a war between an energy corporation and a high-tech criminal army has broken out. Miles's new home in Harlem is at the heart of the battle."
