It follows the former assassin Billie Lurk (voiced by Rosario Dawson[1]) as she reunites with her mentor Daud (Michael Madsen) to kill the mysterious entity known as The Outsider (Robin Lord Taylor).

The game is played from a first-person perspective and the player has access to a variety of supernatural abilities to complete missions in a multitude of ways, from stealth to purposeful violent conflict.

Death of the Outsider was originally planned as a downloadable content for Dishonored 2, but became a standalone expansion after the team decided to explore different approaches with its story and gameplay.

Gameplay elements were reformulated or removed to differentiate the game from its predecessors, adapt it to the standalone expansion format and encourage the player to experiment and explore their choices.

Death of the Outsider was well received by critics, who praised its game design and considered it a suitable conclusion to the Dishonored series up until that point.

[5] After the events of Dishonored 2, Emily Kaldwin is reinstated as empress and begins to salvage the Empire previously broken by Delilah's rule.

On the Dreadful Wale, Daud explains that the Eyeless are in possession of a ritual knife that was originally used to create the Outsider thousands of years prior.

Billie infiltrates the bank and steals the knife, upon which the Outsider appears and reveals that Daud has died of natural causes aboard the Dreadful Wale, to her dismay.

Billie makes her way to an artifact called "the Eye of the Dead God" and absorbs it, allowing her to safely enter the Void portal.

Billie can then either return the Outsider to the mortal realm by having Daud's spirit pronounce his real name, or use the ritual knife to kill him.

Dinga Bakaba, lead designer of Dishonored 2, was one of the initial people arguing for making the Death of the Outsider a standalone title.

[5] Developers felt that removing the need to find elixirs, which were previously required to fully restore energy, encouraged players to experiment more with the full range of powers.

[6] Co-creative director Harvey Smith had concerns about the Semblance power when it was pitched, as he felt implementing the idea appropriately would take an excessive amount of work; ultimately the full extent and ramifications of the power were reduced to more "manageable" levels, and Smith was glad for its inclusion.

Marks praised the "wonderfully detailed" levels and the encouragement to use abilities more liberally, though expressed mixed feelings at the removal of the Chaos system and lack of character progression.
