Unofficial Patch Plus
All Official DLC

New Vegas Script Extender


Unofficial Patch Plus, UP+ or UPP for short, is the premier compilation of supplementary bug-fixes for Fallout: New Vegas, which are not included in Yukichigai Unofficial Patch for one reason or another. Mostly this is because the fixes require NVSE, and YUP follows a philosophy that it should only require the official game and nothing else.

As of version 2.0 UPP is separated into two modules, the first of which contains bug-fixes for elements of the vanilla game only. The second 'addendum' file contains fixes for continuity errors and oversights on the part of the devs, as well as a few other features.

This mod is not a replacement for Yukichigai Unofficial Patch; it is intended to be used in addition to it.

Main File

UPP's main file is for bug-fixes, including updated and improved equivalents to the following mods. I won't reiterate what each of them do here as the original descriptions probably do them more justice. I suggest you check them out for more information.

Using any of the included mods alongside UPP is not recommended, as it may lead to conflicts and/or duplicate effects.

Also, fixes new for UPP are as follows:

  • Repair Kits have been (properly) fixed for weapons with durability mods, and they also play a sound effect, increment the "Items Repaired" stat, and are not consumed when you have no weapon equipped or your weapon is at full health.
  • The "Stimpak's Taken" stat will increment if you use a Stimpak other than the regular variant, e.g. Super Stimpaks or Auto-Inject Stimpaks. This even affects Stimpaks added by other mods.
  • The broken DT multiplication effect from OWB's Big Brained and Brainless perks has been properly fixed. The Marked perk from Lonesome Road is also covered (fix contributed by miguick).
  • Added the vanilla sunguard effect (+1 PER) to some items which logically should have it, and that aren't covered by YUP: Construction Hat, Fire Helmet, Legion Centurion Helmet, Legion Explorer Hood, NCR Trooper Helmet, Police Hat.
  • Swapped 'EnchFourEyesGlasses' effect on some headgear for the unused vanilla 'EnchFourEyesHat' effect, so that the items also give sunguard's +1 PER when you don't have the Four Eyes Trait. The items covered by this are: Legion Prime (Decanus) Helmet, Legion Recruit (Decanus) Helmet, Legion Veteran (Decanus) Helmet, Legion Vexillarius Helmet, NCR Goggles Helmet, NCR Military Police Helmet.
  • XP rewards for all the official DLCs have been corrected so that the originally intended total XP is awarded. Some missing rewards have also been re-added.
  • The Professional perk has been changed to correctly 'catch' mod-added weapons which should be affected by it, but haven't been added to the correct form list.
  • Correctly implemented the broken vanilla Companion Suite perk, which was intended to add abilities for companions as well nerf them slightly.
  • High value items should now actually reach their base value, rather than being a handful of caps below.
  • Fixed Freeside Bodyguards being attacked by Securitrons when approaching the gate to the Strip (fix contributed by Axonis).
  • The original Weathered 10mm Pistol will be automatically replaced with YUP's fixed version when you equip it (as some mods place it in the world, and so circumvent YUP's fix).
  • Changed the value of Gecko Steak from 5 to 4 so that it matches the meat, as is the case with every other steak item.
  • Fixed a bug with the quest objectives in By a Campfire on the Trail if the player approaches the Xander Root after already crafting the Healing Powder (fix contributed by Axonis).
  • Minor name fixes (e.g. "Pre-war Money" corrected to "Pre-War Money").
  • Added the "Glasses" slot flag to Goggles Helmet so it can no longer be equipped with a pair of glasses in order to get the Four Eyes effect twice.
  • Retrieving more than 3 items from a Mojave Express Box now displays a single message, instead of spamming a message for each item. The script has also been modified so that it only counts playable items (fix contributed by Axonis).
  • A couple of miscellaneous form list additions, including some weapons missing from the Grunt perk list, and some items missing from animation lists.
  • Added option to use a customisable hotkey to control the Friend of the Night perk's effects. The effects now fade in and out too, rather than just pinging on and off as they did in vanilla. (This feature is disabled by default; use MCM to assign a hotkey.)
  • Added a customisable hotkey to immediately cancel VATS playback, for those situations when it bugs and leaves you vulnerable for long periods of time.

Addendum File

UPP's addendum file includes fixes for continuity errors and logical oversights. For example, a character may mention something related to the game world which isn't actually the case; or certain items may have a certain trait or use, whereas similar items do not. This file aims to fix these sorts of errors, though they technically aren't bug-fixes. This optional (but recommended) add-on can be found in the optional files section of the downloads.

The mods that are included:

And this file's new fixes are:

  • Trudy's radio changed to play Radio New Vegas, as she refers to Mr New Vegas in her dialogue (fix contributed by Axonis).
  • The radio in the Novac motel room changed to Mojave Music Radio, as it previously received the (mostly-silent) REPCONN launch station (fix contributed by Axonis).

Superseded Fixes

The following fixes are no longer included in UPP as they are now included in Yukichigai Unofficial Patch or better implementations have been accomplished in JIP LN NVSE Plugin or lStewieAl's Tweaks.

Project Nevada Patch

Project Nevada does it again with its needlessly complex changes... The supplied patch makes UPP's changes to the Y-7 Implant work alongside Project Nevada, in addition to patching conflicting aid items.


Recommended Mods

I highly recommend that you use the following bug fix mods alongside Unofficial Patch Plus. These mods are either too complex to include, or are relatively new and I haven't found time to include them yet. Please read the mod authors' descriptions for yourself to understand what they each do.


This mod requires:

You will be notified if any of the NVSE dependencies are missing.

Vanilla UI Plus by axonis is also highly recommended as it fixes several bugs with the vanilla interface and generally improves its usability for modern displays.

Load Order

Load this mod after YUP, and high up in your load order. The addedum file should be placed after the main file, if you use it. If possible, load both files after YUP's NPC fixes file, although don't worry too much about doing this as the effects of any possible conflicts are minor. You can always use FNVEdit to patch these if you wish.

If you're using JSawyer Ultimate Edition, load UPP before it. If you're also using Project Nevada, and the associated patches, your load order should be as follows:

  • Unofficial Patch Plus.esp
  • ...
  • (Project Nevada's.esp files)
  • Unofficial Patch Plus - Project Nevada Patch.esp
  • ...
  • JSawyer Ultimate.esp
  • JSawyer Ultimate - Project Nevada Patch.esp


This mod can be uninstalled at any time and will have no permanent effects on your game.


Many fixes included in UPP are scripted and so will not conflict with anything in most cases. Loading UPP high will mean other mods will 'win' where the two mods change the same record, which will avoid most problems, even though it means you'll lose UPP's fix. I recommend that mod authors copy forward fixes from UPP in the same way as they would for YUP.

If you use a mod which includes a fix which is also replicated in UPP, you may see duplicate effects. For example, if you use another mod which adds the missing Sierra Madre return recipes, there will be two sets of recipes in the menu. The only way to fix these issues is to use a compatibility patch, or for the other author to simply remove the fix so there's no issue to begin with.

Preferably I'd want to avoid making loads of compatibility patches as these take time to make and just clutter load orders and cause confusion. I'd rather this mod become the 'hub' for such fixes and for other mod authors to delegate them to UPP, in much the same way as YUP is considered the de-facto bug-fix mod for conventional bug-fixes. That way, it's simpler for everyone.


I'm happy to take suggestions for changes which should be included in UPP, just be prepared to justify your reasoning. Also keep in mind that I want to keep this as purely bug-fixy as possible, and not stray too far into gameplay changes.

If you think a certain fix shouldn't have been included in UPP then you're free to explain why, and I'll take it on board. Just keep things civil, ok?


The following authors' work was used as inspiration for many of the fixes included in UPP, so all the relevant credit goes to them.
