About this mod

JSawyer's popular mod, fully re-implemented from the ground up. Compatibility has been greatly improved, errors have been fixed, and balance corrections have been expanded - all whilst trying to maintain the original mod's vision.

To me, Josh Sawyer's mod was always seemed like how the game should have been from the start. Of all my many playthroughs of New Vegas (and believe me, there's been a lot), for some reason I always remember my minimalist, vanilla-esque JSawyer runs as the most fun. 

For those not familiar, jsawyer.esp was a mod made by Joshua Sawyer - the lead designer and director for Fallout: New Vegas. It is a difficulty and rebalance mod that maintains much of the vanilla vision, whilst still managing to feel new.

However, it has to be said that the mod might be considered quite crude by present modding standards. There are several errors, numerous inconsistencies, and patching it to work alongside most other popular mods is a nightmare.

That's where JSawyer Ultimate comes in. This mod is a completely reconstructed version of Sawyer's mod, made from the ground up. I've tweaked the odd inconsistencies, expanded the compatibility, and even covered some additional balance issues which were missed - all whilst trying to maintain the fine-tuned spirit of the original.




This mod is a complete, from-scratch remake of the original JSawyer mod. It stays as true as possible to the source material, but cleans up inconsistencies and errors there were, whilst generally refining things and improving compatibility. Examples of errors in the original include:

  • Message and loading screen text didn't reflect some changes to perks.
  • The stats of some items had not been modified whilst similar items had been
  • Some unintentional or ineffective changes were included.

Changes and new additions were only made if I thought that they could be justified from a balance perspective, and if they stayed true to my perceived intentions of the original. A comprehensive changelog is available on the Docs tab of this modpage, which lists every change made by JSawyer Ultimate.

To prevent this description being overly long, I won't completely list the changes and features here. Instead, here is a quick run-down of some of the most notable new features.

Greater Compatibility

Several of the original mod's changes are now implemented by scripts. This means that there will be less compatibility issues, less need for patches, and some features can even be made optional. Moreover, this mod will also cover content added by other mods as much as is reasonably possible. One such feature is that JSawyer Ultimate will automatically adjust stats of mod-added armour so they're not out of place next to Sawyer's tweaks.

Bug Fix Continuity

For all record edits, any appropriate fixes from Yukichigai Unofficial Patch and Unofficial Patch NVSE Plus are included. If a change present in the original JSawyer mod has since been incorporated into YUP, it was omitted from JSawyer Ultimate to prevent unnecessary duplicate edits. Both YUP and UPNVSEP are highly recommended companion mods for JSawyer Ultimate.


This mod can be safely installed and uninstalled on any save - it will not cause a crash or leave any serious permanent side effects.

Un-Cut Content and More

Fallout New Vegas contains many leftovers of features that could not be implemented due to the game's short development cycle, but these give us a glimpse of what could have been. JSawyer Ultimate restores a handful of these features listed below, which are intended to compliment the large-scale restorations of a mod like Uncut Wasteland. Credit for these restorations and features goes to the original authors for their ideas.

Someguy Series Compatibility

JSawyer Ultimate is compatible with all of someguy2000's quest mods out-of-the-box. In addition, some of the overpowered items from said mods will be tweaked so that they're not as powerful, but still worthwhile rewards.

Recommended Mods


JSawyer Ultimate does not require the original JSawyer mod. JSawyer Ultimate was built from the ground up using the original as inspiration, and is entirely separate.

That said, the following are required:

If xNVSE or JIP LN NVSE Plugin are not installed, the mod will still function, but all customisation and some miscellaneous scripted features will be disabled, none of which will greatly affect gameplay.

Unlike the original, JSawyer Ultimate does not integrate the Gun Runners' Arsenal official DLC. This was done so that you may use a different mod to handle GRA, of which there are several, each catering to different preferences. I recommend installing Mojave Arsenal, as this has the option to fully integrate GRA and contains other vanilla-friendly quality-of-life changes relating to ammo and weapons.

If you have already exceeded the new default level cap of 35, you can use my Complete Respec mod to re-level your character to the correct level if you wish.

Load Order

Generally, JSawyer Ultimate should be as low down as possible in your load order, definitely after YUP and YUP's NPC fixes (relevant fixes from all these mods are included).

It's always a good idea to check for conflicts with FNVEdit, too.


JSawyer Ultimate includes an INI file with several options to customise your experience, but comes pre-configured for a balance that stays true to the original mod. Instructions for these options are included in the INI file itself. The INI file can be found in the config folder.


Patches can be found at: JSawyer Ultimate Edition Patches and JSawyer Ultimate Edition TTW Patch.

JSawyer Ultimate edits a lot of game records, but you can ensure that it always wins conflicts by placing it low down in your load order.

Better yet, this mod already includes the necessary Bash tags so that you can load the relevant changes into your automatic Bashed patch using Wyre Bash. This is a very useful tool, and I recommend learning and using it if you are an experienced mod user, as it is significantly more time efficient than making manual merged patches and can automatically resolve conflicts between many mods.


This mod can be uninstalled at any point. The only major permanent change made by JSawyer Ultimate is to enable you to use power armour without training. If you do not have the Power Armour Training perk, you can reset this by typing SetPCCanUsePowerArmor 0 into the console after you uninstall. In addition, if you have the Scrounger perk and have used the ammo rarity option in the INI, you will need to reset the rarity of Scrounger ammo manually by typing set ScroungerOdds to 25 in the console.
