When does Trent Reznor sleep? The dude always has his hands in something, and the newest thing is the upcoming video game Batman: Arkham Knight. Reznor is listed as a musical consultant in the game, and to show they mean business, the first commercial features the Nine Inch Nails track "The Wretched" as it's soundscape:
When the commercial was released, the game producers included a note that said “Please join us in thanking Trent Reznor for his vision.” It's rumored that Reznor helped facilitate a meeting with the game makers and directors Tim Cronenweth and Jeff Cronenweth, who worked as director of photography for Gone Girl, The Girl with the Dragon Tattoo and Fight Club.
No word yet if Reznor contributed any original music to the game like he has done previously on games such as Darkness II and Call Of Duty: Black Ops II.
