After years in development the massive Fallout: New Vegas 'new game' mod Fallout - The Frontier is now available via NexusMods. Set in post-apocalyptic Portland, Oregon, it focuses on a new conflict between the NCR and Legion and promises dozens of hours of narrative in addition to hundreds of new weapons and armour and items. Plus, it's fully voiced.

Here's the release trailer.

In the cold, snowy streets of Portland Oregon, the New California Exiles and Caesar’s Legion fight for the domination of a city rich in resources and military hardware, but what lies in wait under the snowy ruins...

The Frontier is a new game sized modification for Fallout: New Vegas. Created by a passionate group of dozens of community members over a seven year period, The Frontier is the largest modification ever released for Fallout: New Vegas, and aims to be a unique experience for players both old and new.

Featuring new gameplay mechanics such as high quality drivable vehicles, and incredible scripting and visual effects that are sure to impress even the oldest fans of the series. All of this wrapped up with high quality voice acting, dozens of side quests and hundreds of exciting new characters.

With three major factions, a new location, new assets, and new Vaults to discover -- this is one of the biggest, if not biggest, Fallout mod release to date. And it's great to see one of this massive fan projects get a full release too, on the account of the sheer size and scope of many total conversion mods seeing projects like this exist in limbo for years. Be sure to check out the guides on NexusMods as there's a lengthy video detailing exactly how to install Fallout - The Frontier and get it up and running.
