After toiling in development for over seven years, the self-proclaimed "largest modification ever released for Fallout: New Vegas" is now live on PC, and it adds a bevy of new content.

Titled The Frontier, the community-created mod brings over 150 new weapons, three main quest lines (each totaling about 15 hours in length), and additional game mechanics such as driving, all set against the snowy backdrop of Portland, Oregon's ruins. The mod and all it's content is available for free for everyone who owns the base Fallout: New Vegas and its DLC.

In addition to the three new quests, the creators of The Frontier said that the mod also packages The New California Republic mission. While it's unclear if this quest is part of the three new missions or an additional one (making four new quests total for Fallout: New Vegas), the developers did confirm that The New California Republic sits at about 35 hours long.
