The Mojave might never sleep, but it’s finally getting a new neighbor. Fallout: Long 15 is an ambitious upcoming mod for Fallout: New Vegas that lets players venture west into the homeland of the New California Republic.

Developed by the same team behind Dry Wells – Legion Expansion, Long 15 promises a massive new world filled with new towns, factions, and quests. The Dry Wells mod was praised for its polish and depth, which makes this new project even more exciting.

Check out the short trailer above while waiting for the full story trailer, which is supposed to drop in late November or early December.

Long 15 is set to release December 12, 2025 and should be available right here when it gets released.
