The news was announced at an event we attended, during which time we also got the opportunity to go hands-on with the new Batmobile Though the game was originally due out on PS4, Xbox One and PC on October 14 this year, it seems the developer has had a change of heart. No reasons for the delay were given, though it's safe to assume the studio wants to make sure it goes out with a bang. On the plus side, with October and November this year already looking busy, it's probably not the worst thing in the world.A range of villains have already been confirmed for the title, including Riddler, Penguin and Two-Face . We also know Harley Quinn is set to appear in the upcoming climactic chapter to the Arkham series, and pre-ordering will let you play as her . Kevin Conroy is confirmed to return as Batman , while Troy Baker has strongly hinted he'll once again lend his pipes to voicing Two-Face For our latest impressions on the game, check out what we were left thinking when Rocksteady gave us the keys to the Dark Knight's wheels
