It may not have looked like it, but Suicide Squad: Kill the Justice League’s world is the same one where the Arkham games took place.
Suicide Squad: Kill the Justice League developer Rocksteady has confirmed that the game does indeed take place in the Arkham universe the studio established all those years ago.
This is interesting because although Batman does not show up, it is assumed that the Harley Quinn seen in the reveal trailer is the same one we ran into in the Arkham games. In fact, according to Rocksteady co-founder Sefton Hill, Suicide Squad will continue certain plot threads from those games.
That said, Kill the Justice League does, of course, take place in Metropolis rather Gotham, so you shouldn’t every character from Arkham to show up.
“This is a continuation of the Arkhamverse, so a lot of the threads and storylines you’re going to see come to fruition in this game,” said Hill, though without elaborating any further beyond that.
This is the inverse of the Gotham Knights situation, where players immediately assumed the story takes place after the events of Arkham Knight, only for developer WB Games Montreal to clarify that it does not, and is in fact set in a new world separate from the Arkham games.
Suicide Squad: Kill the Justice League is much further away than Gotham Knights, so expect details on the former to be fairly slim compared to the latter going into next year. The game is in development for PC, PS5 and Xbox Series X.
