Thanks to a Bloomberg report, Rocksteady never pitched or worked on a Superman game despite it being a popular rumor. After the studio finished working on Batman: Arkham Knight in 2015, it started working on Batman: Arkham VR.

Following that, the studio reportedly began to work on an unannounced multiplayer game that had nothing to do with the Arkham universe. Then, in 2016, Warner Bros. studio in Montreal canceled a Suicide Squad game after the project was handed over to Rocksteady.

Suicide Squad: Kill The Justice League is set in the same universe as the Arkham franchises. In the upcoming game, you'll play as one of four DC villains in the Suicide Squad, and as the name suggests, you'll be tasked with killing the Justice League. Unlike the Arkham series, Suicide Squad will take place in Metropolis, which is also the home to Superman. In addition to that, it'll also feature the late Kevin Conroy as Batman.
