For those of you who don’t know, ever since the frontier mod launched, new Vegas has gotten many map expansions. Most of the mods I’m going to list expand the games default map:
NV interiors project
NV interiors project remastered
Freeside interiors
Open Mojave
<as the names imply, these mods add new interiors to the game world and they integrate entire locations to the base game world seemlessly respectively.
Nova Arizona expansion
<effectively doubles the size of the base map by making the eastern portion traversabke with new quests
Dry wells
<another legion expansion mod that makes the northern part of the map accessible with new quests
Long 15 before the remaster
<made in 2010s. Allows you to explore the far wests without needing to complete lonesome road
The new expansion is going to add a brand new location to the Mojave wastes. Now you get to do NCR quests in it. The community has been developing the mod for years, and I’ve seen a lot of good stuff come out of it. New Vegas almost feels finished with this new expansion.
