Batman: Arkham Origins developer Warner Bros. Games Montreal currently has "two AAA projects in development focused on expanding the DC Comics universe", a job ad for the studio has revealed.
While neither game has yet been announced, it's possible that one of the two projects could be the PS4 and Xbox One Batman: Arkham Collection rumoured by VideoGamer.com earlier in the year. The studio has also been linked to an unannounced Superman game and a Justice League title, although neither have been confirmed by publisher Warner Bros.
Unfortunately, none of the studio's job ads offer any hints as to what the game could be either, although they suggest it could be coming to PS4, Xbox One and PC.
WB Games Montreal's first title Batman: Arkham Origins launched on PS3, Xbox 360 and PC back in October 2013. It later developed the Batgirl DLC for Batman: Arkham Knight.
