With the announcement last week that 4A Games are already working on a sequel to Metro Exodus, Dmitry Glukhovsky, author of the Metro book series, took to Instagram to confirm his involvement in the next game’s story.

This comes as a treat for fans of both the novels and the games, as Glukhovsky was last involved in 2013’s Metro: Last Light. In lieu of Glukhovsky, Andrew Prokhorov took care of Metro Exodus’ story. There’s no word on if the next Metro game will be based on another Metro novel.

Meanwhile, Metro Exodus upcoming DLC, “The Two Colonels”, will be shown off at Gamescom tomorrow night. In fact, you can watch the reveal on the Inside Xbox stream.
