The creators of a gigantic total conversion mod for Fallout: New Vegas have delivered a progress update. Fallout: New California, intended as a fan-made prequel to New Vegas, has been in the works for over seven years now (though it’s only been a properly announced project for the past five years). New California‘s developers celebrated the fifth anniversary of their project by releasing a narrative trailer for the mod, and a solid release date.

Fallout: New California takes place in the ruined city of Los Angeles, with players taking the position of a resident in Vault 18. After what looks like a bit of a crisis in the vault, player characters emerge into the ruined world amidst a power struggle. In the trailer, the New California Republic, the Survivalist Army, and of course the Supermutants, are squabbling over territory with the player character caught in the middle. The player’s actions “shape the politics and events leading to the NCR’s invasion of the Mojave,” according to the mod’s Mod DB page. New California takes place in 2260, roughly 21 years before the events of New Vegas.

The mod’s full campaign “will contain 16 Main Quests and several side stories,” and its development team confirmed that the mod is now art-locked (all art assets have been locked in). Despite that, the team will be taking another few months before release to integrate side quests. “…You hit this story with huge replete branches 16,000 lines of dialogue deep and you expect some little moments with characters off to the side of the big arcs, and there just aren’t that many of note,” wrote project lead Brandan Lee for the latest mod update. “I’d also like to take time to revise some plot holes and gaps in the open possibilities that appeared in testing, and more streamlined opportunities for branches that aren’t so hidden in past decisions.”

Beta sign-ups to test the mod will be available in July, though only the main quest line and associated areas will be playable in the beta. Fallout: New California‘s full release (though they’re still calling it a Beta 2.0.0 release) is happening on October 23, 2018.
