Fallout: New Vegas shipped with significant bugs and no sprint mechanic, and a long-running modding scene has addressed both. The question is where to start. The answer below follows the Viva New Vegas guide, which tells you to read everything and follow it in order. Its introduction says you cannot skip paragraphs or instructions and expect the game to work as it should.

Checked October 16, 2026 against the guide’s own pages. The requirements and Wabbajack notes were re-checked against the guide’s introduction and Wabbajack pages on October 21, 2026, and the base-install mod list against PC Gamer and Nexus Mods on October 22, 2026 and against the guide’s Bug Fixes page on November 3, 2026.

What Viva New Vegas is

Viva New Vegas (VNV) is a modding guide, not a mod pack. It walks you through installing the mods for a stable, smooth experience. The guide is split into two sections:

  • The base guide contains the mods the game needs in order to work and perform better. Its pages cover utilities, bug fixes and a base finish step.
  • VNV Extended contains the subjective mods that change or add content, and it is fully modular, so you can skip parts you do not want.

The guide also has a Wabbajack page for automated installation instead of the manual step-by-step setup. That page says only Steam (Global) and GOG copies of the game are supported by the Wabbajack version, so check which storefront you bought from before you choose that route. PC Gamer’s New Vegas guide also names Viva New Vegas as its top recommended mod pack and notes that it is available again through Wabbajack.

What you need first, per the guide’s introduction:

  • An English copy of the game with all DLCs from Steam, GOG or the Epic Games Store. The Microsoft Store versions are not supported.
  • Windows 10 or higher, 64-bit, and at least 19GB of free drive space with the game included, or 17GB if you delete the downloads afterward.
  • A Nexus Mods account. A Premium subscription allows uncapped download speeds.
  • A text editor, an archiving tool and the latest GPU drivers.

What the base install includes

PC Gamer’s guide names four key mods of the most basic Viva New Vegas install, which it says focuses on patches, fixes and some quality-of-life changes:

  • Yukichigai Unofficial Patch: PC Gamer says it irons out thousands of small errors.
  • Unofficial Patch NVSE Plus: it uses script extenders to fix more issues. Its Nexus Mods page describes a collection of mostly NVSE-based bug fixes meant to be used alongside the Yukichigai Unofficial Patch, and says it supersedes the earlier Unofficial Patch NVSE and Unofficial Patch Plus.
  • Improved AI: it cleans up pathfinding issues that hampered combat.
  • Iron Sights Aligned: it makes bullets go where they should when you aim.

PC Gamer describes this set as restoring the game’s foundation rather than adding content, and says most of it is slotted in with Mod Organizer 2.

That list comes from PC Gamer. The guide’s own Bug Fixes page, which we opened on November 3, 2026, lists Yukichigai Unofficial Patch (which it describes as fixing thousands of bugs in the base game and DLCs), Unofficial Patch NVSE Plus and Iron Sights Aligned, so those three are confirmed. We did not find Improved AI on that page, so PC Gamer’s list may be older than the guide, or Improved AI may sit on another page. The Bug Fixes page also lists about two dozen other fixes in its main section, including lStewieAl’s Tweaks and Engine Fixes and the New Vegas Mesh Improvement Mod, plus ten optional minor fixes. Follow that page for what the guide installs today.

Where sprint and quick looting come from

Sprint and quick looting are not in the vanilla game, and in VNV they sit in the optional Extended section. The guide’s Gameplay page lists:

  • JAM (Just Assorted Mods). It adds configurable modern features. VNV’s preset uses a dynamic crosshair, hit markers, hit indicators, a Fallout 4-style loot menu that opens when you look at a container, and a quick-use wheel. JAM’s own sprinting is disabled by default in that preset because Enhanced Movement replaces it.
  • Enhanced Movement. A movement expansion with enhanced sprint, enhanced sneak and leaning. The guide gives recommended settings for sprint speed bonus, agility speed bonus and action point cost.

The same page lists several smaller additions, including Manual Reload and Ammo Memory, Cookable Grenades, Faster Sleep-Wait, an Auto-Save Manager and Better Caravan.

Content and balance mods

The guide’s Content page lists The Living Desert, which adds hundreds of new NPCs and scripted events, Better Brotherhood, and Goodies, a collection of restored content, consistency fixes and gray-area bug fixes.

For balance, the guide recommends Agua Fria - JSawyer Redone, which it describes as a reworked version of the original JSawyer rebalance. It lists lower starting Health and Carry Weight, slower leveling, a lower level cap and a rebalanced Hardcore mode among its changes. The introduction calls it not recommended for first-time players.

Other well-known mods, such as open-Strip or power-armor overhauls, are not part of the guide. Their installation order and compatibility with the VNV setup are not covered by the sources checked, so test them yourself and read each mod’s page before adding them.

The remaster

On July 17, 2026, Bethesda Game Studios confirmed that it has been working on remasters for both Fallout 3 and Fallout: New Vegas, as GamesRadar reported, without announcing dates. VGC adds that no gameplay footage or screenshots were shown. The sources checked do not mention mod support, and we found no newer announcement of dates as of October 21, 2026, so this guide applies to the original game. For more on the announcement, see Fallout New Vegas vs. Fallout 3 Remaster.

Which route we would pick

The sources above decide part of this for you. Wabbajack supports only Steam (Global) and GOG copies, while the guide’s requirements also allow an Epic Games Store copy, so an Epic owner is left with the manual route. Microsoft Store versions are not supported.

If you can use both, the guide presents Wabbajack as the automated alternative to the manual setup. Our reading is that fewer manual steps leave fewer places to make an ordering mistake, and the guide warns that skipping steps will stop the game from working as it should. We found no source comparing how often each route fails, so this is a judgment, not a finding.

Two choices we would make on a first run:

  • Leave out Agua Fria - JSawyer Redone. The guide’s introduction calls it not recommended for first-time players, and it changes starting Health, Carry Weight, leveling and the level cap.
  • Add Extended modules in small groups. The guide says Extended is fully modular. Playing for a while after each group makes a problem easier to trace. This is our suggestion, and the guide does not say it.

Questions readers ask

What are the essential mods for Fallout: New Vegas? The base guide’s mods: patches, bug fixes and a base finish step. The guide’s Bug Fixes page confirms Yukichigai Unofficial Patch, Unofficial Patch NVSE Plus and Iron Sights Aligned. Sprint and quick looting come from optional Extended mods.

Does the guide work with a Microsoft Store copy? No. The guide’s introduction says Microsoft Store versions are not supported. It lists Steam, GOG and Epic Games Store copies with all DLCs.

How much space do I need? The introduction says at least 19GB of free drive space with the game included, or 17GB if you delete the downloads afterward.

Will the remasters replace this guide? Bethesda confirmed the remasters on July 17, 2026 without dates, and we found no newer announcement as of October 21, 2026, so this guide applies to the original game.
