At the reveal of the $40 Season Pass for Arkham Knight, gamers got a little annoyed. Main reason being they didn’t mention anything about the contents of the DLC, just the hefty price point.
Responding to the backlash, Warner Bros. responded accordingly (cited by GameSpot):
"We’ve heard from our community that you want more information on what we’ll be delivering in the Season Pass. While we aren’t ready to unveil every aspect of the content we’ll be developing, we would like to share more detail now to give you a better sense of the scope of the Season Pass."
