Dishonored: Death of the Outsider, developed by Arkane Studios, is a standalone expansion to the Dishonored series that allows players to step into the shoes of Billie Lurk as she navigates the corrupt city of Karnaca.

This guide will provide a detailed walkthrough of all hidden content, uncovering the secrets that make Death of the Outsider one of the most intricate entries in the Dishonored universe.

Introduction — Why Exploring Hidden Content is Essential

Dishonored: Death of the Outsider isn’t just about assassination and stealth; it’s about uncovering the layers of Karnaca’s shadowed alleys and hidden motivations of its citizens.

Players who fully explore the game experience a richer narrative and gain access to exclusive tools and gameplay advantages.
