Which Arkham Origins mode ends the game if Batman dies?

I Am the Night is the Arkham Origins mode that ends the game if Batman dies.

This mode is designed as the game’s most punishing single-player challenge. It becomes available after the player completes New Game Plus, which itself is unlocked by finishing the main story. I Am the Night retains the campaign’s world and combat systems but makes survival the central condition of success.

The defining rule is effectively a permadeath constraint: Batman’s death ends the run instead of simply sending the player back to a routine checkpoint. That makes ordinary mistakes—particularly during difficult predator encounters, boss fights, or traversal sections—far more consequential than they are in the standard campaign.

Hunter, Hunted is an easy mode to confuse with it because that title also sounds like a survival challenge. However, Hunter, Hunted is a multiplayer mode involving Batman, Joker gang members, and Bane gang members. New Game Plus is also different: it gives players a tougher replay with existing abilities, while I Am the Night adds the run-ending death rule.
