Batman: Arkham Knight will close out Rocksteady Studios' hit game series with a bang and, it seems, an "M for Mature" rating.
IGN reports that while previous games -- Arkham Asylum, Arkham City and Arkham Origins -- were rated "T for Teen," the Entertainment Software Rating Board (ESRB) determined this chapter is suitable for ages 17 and up, to the surprise of the developers.
"From our point of view, we never wrote it or made it with a rating in mind," Rocksteady founder Sefton Hall told the website. "We never did that in the previous two games ... We just felt that this is the story that we really wanted to tell."
Although he acknowledged the rating may mean some younger fans won't be able to play Arkham Knight, Hall said it would've been "wrong to water down the game" to appeal to the mass market. "We're not including gratuitous blood or swearing," he added. "We want to deliver a true end with no compromises, and it takes us to some dark places."
Scheduled for release June 2 from Warner Bros. Interactive Entertainment, Batman: Arkham Knight follows the Caped Crusader at the peak of his abilities, as Scarecrow returns to Gotham City to united his foes to finally kill the Dark Knight.
