Der er fire karakterer du kan spille som i det kommende Gotham Knights, og det skyldes at der primært er fokus på kooperativt spil. Du kan spille alene, selvom fjenderne er designet til netop co-op, men hvis du gør, så stiger de andre karakterer du ikke bruger automatisk i niveau samtidig med den du faktisk bruger.
Dette er blevet bekræftet igennem et interview med GamesRadar, hvor Creative Director Patrick Redding og producer Fleur Marty siger:
"Since the story progression is shared between all the characters, it also makes sense that you don't have to level them up from scratch every time you want to switch. It also stays very coherent in terms of our narrative.
Since the other members of the Batman family are always present in some way in the background, while you're out in the world fighting crime or unraveling the mystery, they don't stay inactive. So it makes sense that they are also progressing and getting stronger."
Du kan altså frit skifte imellem Batgirl, Nightwing, Red Hood og Robin, og have dem klar til næste led af historien. Hvad synes du om det?
