DC executives have been talking to Rocksteady and NetherRealm about creating new games in a single universe, but they haven't disclosed any details

DC Studios CEOs James Gunn and Peter Safran have held talks with Warner Studios, including Rocksteady and NetherRealm, to develop new games based on the DCU universe.
Here's What We Know
In January of this year, DC announced the creation of a unified media universe that will include video games with the same stories and characters as in films, TV series and animation.
During a recent DC Studios event, Gunn and Safran spoke about their close collaboration with J.B. Perrett, CEO of Warner's global streaming and games business.
Gunn noted that they are actively involved in the development of new projects at the early stages, discussing characters and stories that interest both parties. The first DCU game will be released in a few years, but there are already several interesting projects in development.
There are also rumours that Rocksteady is working on a single-player Batman game, although it is not yet known whether it will be a new part of the Arkham series or a part of the DCU. In addition, a Wonder Woman game from Monolith Productions, announced in 2021, is also in development, although its release has been delayed due to the 2024 relaunch.
