Fallout: New Vegas mod adds a Dark Brotherhood-inspired assassin faction to the Mojave

A new Fallout: New Vegas mod called Twilight Eternal transplants the Dark Brotherhood from Oblivion into post-apocalyptic Nevada as a new joinable faction called the Dark Family. The mod is live on Nexus Mods now.

The Dark Family comes with its own bunker base, a full main questline, and an infinite loop of repeatable assassination contracts. Mr Burke — the Tenpenny Tower-affiliated villain from the base game — steps into the Lucien Lachance role, visiting you in your sleep after you kill your first innocent target and inviting you to join up. Complete the main questline and you get a player home. If you just want the murder-for-hire grind, ColdTyrant says the contract system has around 10,000 combinations of target, location, and bonus objective.

The modder behind this, ColdTyrant, built a reputation adding radiant faction quests to Oblivion Remastered shortly after that game launched last year. Twilight Eternal is part of a broader project to do the same for New Vegas and Fallout 3's factions — bringing structured, repeatable content to guilds and groups that the base games left underserved. The Dark Brotherhood is one of the most beloved factions in Elder Scrolls history, so mapping its structure onto the Mojave is a natural fit for players who want more assassination-flavored roleplay in New Vegas.

The mod is available on Nexus Mods now. Given ColdTyrant's track record with the Oblivion Remastered work, more faction quest mods for New Vegas and Fallout 3 are likely still in the pipeline.
