The Fallout: The Frontier mod contains an open world, comparable in size to the wastelands of DC, in which there is a snow-covered Portland with real sights and locations. The team implemented a vehicle system, added many types of opponents, over 150 new weapons and hundreds of items of equipment.

In addition, the Fallout: The Frontier mod contains modern visuals. They are built to be as performance-friendly as possible while still delivering quality graphics. Fallout: The Frontier characters have been fully voiced – more than 24 thousand lines of dialogue, which were read by talents from the Creators Network and Casting Call Club. In terms of quests, the modification includes three main quest lines: for the NCR, the Legion, and the Brothers of Steel. There are also dozens of side quests of varying duration and difficulty.

Finally, the Fallout: The Frontier team has published a list of Fallout: New Vegas mods that have been tested for frontier compatibility.
