Bethesda Softworks announced today that Arkane Studios is working on Dishonored: Death of the Outsider, a standalone chapter in the main series, scheduled for release on September 15th. The new game will follow assassins Billie Lurk and Daud as they attempt to kill the Outsider, a seemingly divine entity who is responsible for the events that transpired during Dishonored and its sequel.

This is not the first time we’ve seen Billie Lurk and Daud working together, since the former was introduced as the latter’s protege in The Knife of Dunwall and The Brigmore Witches (Dishonored‘s two story-based downloadable content pieces)

Take on the role of Billie Lurk, once one of Dunwall’s most notorious killers-for-hire. Reunited with your old mentor, the legendary assassin Daud, you undertake the greatest assassination ever conceived: killing the Outsider, a god-like figure whom Daud sees as instrumental in some of the Empire’s most dishonorable moments. As you venture deep into the grimiest corners of Karnaca to uncover the mystery of the Outsider and his origins, face deadly opposition, dark ancient powers, and difficult decisions that will forever change the world around you.

Dishonored: Death of the Outsider is a first-person action game that features all the series hallmarks, including brutal combat systems, unique level design, and immersive storytelling that responds to your every choice. With compelling characters and exhilarating action, Dishonored: Death of the Outsider is the perfect entry point for those new to the series, while delivering a significant expansion of the gameplay and world for longtime fans.
