Unlike its predecessor, Batman: Arkham City features a New Game Plus mode, developer Rocksteady Studios has confirmed.
According to a post on the game's official forum, the mode will unlock when you finish the game on either the Normal or Hard setting.
You'll then be able to play through again with all your gadgets, XP and unlocked upgrades intact.
However, no counter icons will appear on enemies, tougher foes will be available from the start of the game, opposition will be configured differently and bosses will be harder to take down.
New Game Plus will be the same difficulty regardless of whether you finished the game on Normal or Hard.
