Grab your winter coat, assault rifle, and some Nuka-Cola! Fallout: The Frontier, a massive Fallout: New Vegas mod that will allow players to explore the post-apocalyptic city of Portland, Oregon, is releasing today after seven years of development.
Set in the snowy, post-apocalyptic city of Portland, Oregon, Fallout: The Frontier takes place around the same time span as the vanilla game's DLC side areas and, like the official DLC, has players controlling The Courier. The mod has three main quest lines themed around the northern branch of Caesar's Legion, a band of exiled New California Republic forces, and a splinter faction of the Brotherhood of Steel. Each of these factions is vying for control of Portland, a valuable target for its resources and military hardware, but something else may be lying in wait under the snowy ruins. In total, each main storyline has over 15+ hours of content, with the NCR's clocking in at 35+ hours.
One of the biggest features in Fallout: The Frontier is the ability to use vehicles to travel and battle, a feature not seen in vanilla Fallout games. The "Gameplay" section on the official website also hints that players will be able to get into airborne dogfights. For those more interested in the story of The Frontier, the FAQ explains that the team chose Portland due to it being a "completely new environment from the Mojave Desert and Capital Wasteland." The area around Portland doesn't have much in the way of the official story, so the team worked to make the story fit the lore while also creating backstories that connect the Mojave to the Frontier. On the topic of Vaults, the apocalypse shelters / human experiments, the FAQ says that there will be Vaults in The Frontier, but they can't spoil too much about them.
How does Fallout: The Frontier work with other Fallout: New Vegas mods?
Unsurprisingly given its size, Fallout: The Frontier has a variety of mods with which it doesn't work properly. The team has compiled a spreadsheet featuring a variety of mods and more info on them, such as if The Frontier is dependant on them or if you should use a similar mod instead. The spreadsheet isn't comprehensive though, and there's a second link in the spreadsheet featuring more mods to avoid if you're planning on visiting Portland.
