What is the name of the secret ending in Batman: Arkham Knight?

The secret ending in Batman: Arkham Knight is called the Knightfall Protocol. Batman activates it after Scarecrow publicly exposes Bruce Wayne’s identity and Batman has secured Gotham’s immediate safety.

The protocol is designed to protect Batman’s loved ones by ending Bruce Wayne’s public life and removing the Wayne family from the spotlight. In the ending sequence, Batman returns to Wayne Manor with Alfred, and the mansion explodes, apparently killing them. The game does not explicitly confirm every detail of what happened, which is why the ending has inspired extensive fan discussion.

Afterward, Gordon prepares for Barbara Gordon and Robin’s wedding, while a mysterious figure resembling Batman appears to confront criminals in Gotham. This final image suggests that Batman’s mission may continue, whether through Bruce Wayne himself or a successor. The title also echoes the 1990s Batman storyline Knightfall, in which Batman’s role is temporarily taken over by another crime-fighter.
