Dishonored: Death Of The Outsider will introduce a new type of missions called Contracts and while these missions are optional but, players will only have one chance to play. Contracts are basically side-quests that players can take on for money, however, whether you fail or succeed, you will have only one chance to complete them.
According to creative director Harvey Smith, these Contracts in Dishonored: Death Of The Outsider are similar in scope as to Favors for Daud in the Knife of Dunwall and The Brigmore Witches expansions in the first Dishonored. He added that these missions are stranger in nature compared to the traditional Dishonored missions.
Contracts are a new system dreamed up by the Arkane team members in Lyon, France. We felt like mercenary contracts were the right call for Billie as a new featurette, just like adding Favors felt right for Daud in the Knife of Dunwall and the Brigmore Witches, since Daud had years of experience running an underworld organization, and presumably a bunch of people owed him blood debts. Most of the time, contracts can be found and undertaken in black market shops across Karnaca. They’re often stranger in nature than most Dishonored missions.
Furthermore, these Contracts can take place in entirely different locations from the main game. Some contracts will take players to another part of the world that is not included in the main story or missions.
Often, contracts will pull you over to another part of the world, away from the main mission, so you get a chance to see something tertiary, and when you move back toward your primary objective, you see the situations along the way from a different angle.
In related news, Arkane Studios has confirmed that Dishonored: Death Of The Outsider is the finale of the Corvo and the rat plague arc, meaning Corvo and Emily might not be featured in future Dishonored titles.
Dishonored Death Of The Outsider is a standalone DLC for Dishonored 2 and is scheduled to launch on September 15, 2017, for PC, Xbox One, and PlayStation 4.
