Fallout: New Vegas/Unused Items

To add these to your inventory, type player.additem [base id] 1.

Also, note that many items, keys, and a few enemies, NPCs and locations from FO3 reappear in NV's code. The base ids for all the items are identical in both games.

Armored Vault 21 Jumpsuit
An armored version of the V21 suit, like the armored V101/V13 suits. +5 Guns, +3 Energy Weapons. Considering how nonsensical it was that you got the regular V21 suit, it's no loss that this was cut. You can still see the armor being worn by the courier in some of the very last ending slides. Base ID: 1046f8

Chinese Stealth Helmet
Accompanies the armor which you can find in Hoover Dam. The helmet is actually built into the suit, so this is unnecessary. Has the same world object and Pipboy icon as the Recon Helmet. 15fd5d

Remnants Tesla Armor
Enclave power armor similar to the one you get for helping Arcade Gannon with his quest, except it's got tesla coils on the back. Gannon will wear an identical looking piece of armor in the final battle if you get his help, but it's actually a completely different item. Body: 133f31 Head: 134094

Repconn Jumpsuit
Other than the fact that all the REPCONN employees are dead, there's no real reason why this shouldn't have made it in. Note the uncapitalized name. When dropped on the ground it looks like a RobCo. Jumpsuit. 153a0e

Vault 24 Jumpsuit
Has the same stats as every other vault jumpsuit, except there's a 24 on the back. Vault 24 doesn't appear in the game and wasn't even mentioned in any supplemental materials. It is possibly a vestige of a cut location. Its Pipboy icon is darker than those of the other vault jumpsuits. 1300b0

Papa Khan Helmet and Armor


This helmet and this armor can be find on a second Papa Khan NPC who is unused. Stats of these items are incomplete and the texture of the armor is missing. Armor: 15a937 Helmet: 15a935

Underwear
Uses the same skin as the Vault 101 Jumpsuit from FO3 for male characters, and as glued-on underwear for female characters. 89b52

White Mask
Graphically identical to the White Glove Society Mask. Repaird by and uses the Pipboy icon of the Raider Arclight Helmet. Weighs three times as much as the WGS Mask, but does not disguise. 11a970

Eagle Flag Pole


Contained in the first-person view models for the weapons. Probably would have been animated like the Pool Cue and similar weapons. It was later included as an item called "Old Glory" used by Ulysses in the DLC expansion Lonesome Road.

Stun Grenade
Inflicts fatigue damage like the boxing gloves. 14dddf

Unique Multiplas Rifle
The model for the Multiplas Rifle that is actually used in-game is not the one that was originally intended for the weapon - it's the unique version. The image above it the original Multiplas Rifle, which went unused. Since there was no model for the unique Multiplas Rifle, it never made it in the game.

Deathclaw Gauntlet
The armor-piercing homemade claw weapon from Fallout 3 was set to make a return, and with heavily modified stats (unlike other recycled FO3 items) but didn't make it into the final version of the game, making Deathclaw Hands useless. There was however a unique version of the Deathclaw Gauntlet included in the Lonesome Road DLC 432b

Debug MegaPistol
A 9mm pistol which inflicts 9999 damage per hit. I wonder why this was cut. 1465a6

The Disintegrator
A laser rifle which inflicts 1000 damage per hit and always critical hits, so it always turns the target into a pile of ashes. f82aa

Gas Grenade
Looks just like the regular hand grenade. Releases a plume of smoke upward when thrown. Inflicts only one damage. 12701f

Plasma Rifle
There are three items with this name in the game's files, two of them unused. The first is called HVWeapPlasmaRifleWeak internally, and just as its name suggests, it's weaker then the regular Plasma Rifle. The HV prefix in the name means it was intended for use in Hidden Valley, probably as another broken weapon like the Jammed Minigun. The other is named WeapPlasmaRifleAlwaysCrit, which functions more like a Multiplas Rifle, except like the Disintegrator, it always crits and always turns the target into a puddle of goo. Both unused rifles look identical to the regular version. Weak: cda5c Always Crit: f7eae

R9000 Camera
A clone of the Codac R9000. Uses small energy cells. 13621d

In Name Only

 * Double Barrel Shotgun: Its repair list can be found in the GECK's form lists, but there is no other evidence of its existence. It's probably safe to assume that this would have been the same as the double-barreled shotgun from Fallout 3 GOTY.
 * General Purpose Machine Gun: Has its own unused repair list. Might have been an early name for the Light Machine Gun (which has its own list) but probably not.
 * Heavy Riveter: Has an unused repair list. A giant nail gun would have been a cool weapon. Utterly baseless speculation: Might have nailed enemy ragdolls to the wall like some other popular weapons (e.g. Painkiller's Stake Gun).
 * L.A.E.R.: Laser-assisted Electric Rifle. Has a concept art in the collector's edition strategy guide; the only in-game evidence of its existence are leftover actor and object effects in the GECK. Later added as a weapon in the DLC expansion Old World Blues.

Marksman Carbine Extended Magazine
Unfortunate, as the Marksman Carbine has no mods in the game.

Service Rifle Bayonet and Reflex Sight
Their graphics exist, but the specifics for the mods themselves are incomplete. How the bayonet would have worked is a mystery since there are no combination melee-firearm weapons in the game.

Trail Carbine Laminate Stock and Custom Action
Would have reduced the carry weight and increased durability, respectively. There are junk item versions of all three mods which do absolutely nothing. Custom Action: eea6f Laminate Stock: eea6e Scope: eea6d

10mm Pistol Heavy Frame
The name of the mesh for the default 10mm view model lists it as a 'Heavy Frame' mod in the GECK. There is no mesh for a non-Heavy version. The mod, if it existed, would have increased the durability.

.44 Special
Ammo for the .44 magnum revolver and trail carbine. Despite being unused, it is still mentioned on the loading screens occasionally. The 1.2 patch added a single box of them to the NCR safehouse. 15e8ed

Hunting Rifle Stripper Clip
Listed in the GECK's viewmodels in name only. The mesh doesn't exist.

Spore Plant Pods
A minor healing item which increases poison resistance. Would have been dropped by the spore plants in V22. Likely cut because their exclusive location meant there would be no reliable way to find these without trekking down to the vault's basement. You can find one of them on the ground in the test map. They can however be found in Honest Hearts and Old World Blues areas. e2f69

Fruit Mentats
These are the three special flavored mentats from Fallout 3: Berry, Orange, and Grape. There are signs they were meant to return in New Vegas at some point - all three are on the list of items banned by Caesar's Legion. Instead of bringing back three items which were virtually the same, they introduced Party Time Mentats which are much more helpful. Berry: bf7c6 Grape: bf7c5 Orange: bf7c7

Irradiated Radroach Meat
Called just 'Radroach Meat'. Has 8 more rads than the regular kind. 13215b

Leg. Healing Powder
Like the regular powder, except it heals 3 hp/s for 27 seconds. Not unused, but there's only a window of a few seconds for the player to use it because it's held by Legate Lainus. Uses the world model for Buffout. 14c11c

Mole Rat Wonder Meat
A food item the player could produce in one location in Fallout 3. Probably intended to be a campfire recipe at one point, as its stats were adjusted to reduce starvation for hardcore mode. There is a single piece in the game, in Cannibal Johnson's cave. abd17

Nuka-Cola Quantum
Another Fallout 3 leftover adjusted for hardcore mode and featured on the Legion's contraband list for some reason. Likely cut due to because of Quantum's region-specific nature. 284f9

Scorpion Poison
Puts Radscorpion poison on the player's weapon. World model is identical to Absinthe. Also on the Legion's contraband list. 13d60f

Scorpion Poison Grease
Identical to above. 15bd07

Sweetroll
The Elder Scrolls running gag from FO3 was meant to return at some point, likely at character generation. The item's stats were also adjusted for hardcore mode.

testfx
Test item. Inflicts one 'hiss' of Cazador poison on the player. Uses Psycho's mesh and carries a risk of Psycho addiction. 1598ef

Aster's Journal
This would have gone in Hidden Valley so Aster was almost certainly Brotherhood of Steel. 16007f

Barnabas Bear
A teddy bear intended for use in Bitter Springs. The line "I like you. Will you take Barnabas Bear to New Vegas when you go?" is attached to this item. 13abdc

EggTimer
Duplicate of Egg Timer (with a space). 154308

GawdyGnome
An evil gnome identical to the unique one you find in Fire Root Cave, but with a different GECK name. The Evil Gnome's GECK name is "ScottEGnome", named after one of the developers. 15e013

Mayor Steyn's Journal 1/2
You can read this on his office computer, but not pick it up anywhere. 13722c

NCR Ranger Station Logs
Items relating to the quest 'Return to Sender'. The only one which made it into the game is the GBRM2KX Memory Chip, which is in the inventory of a Robobrain at RS Delta.
 * Lineholm's Log (Alpha): 1210f9
 * Ericsen's Log (Bravo): 1210fa
 * Charlie Station Supply Manifest: 1210fb
 * Erasmus's Logbook (Echo): 1210fd
 * Kudlow's Report Log (Foxtrot): 1210fe

Platinum Chip
The actual chip is called "The Platinum Chip" in-game. 11678e

Recipes - Ruby's Spicy Casserole
This is a junk item, not the functional (unused) note. Item: 1613d3 Note: 1613d1

Schematics - Mantis Scythe
Probably referring to the weapon Mantis Gauntlet. It was was quite obviously intended to be craftable, but for some reason they forgot to implement the recipe. efb3c

Sentry Bot Toy
Uses the model for the Ash Tray internally, but if dropped by the player it creates a fully functioning Sentry Bot Toy (or a broken one, see unused creatures). At some point in development you would have found a tiny Sentry Bot you could pick up. If you killed it first you'd get a broken version. The item and creature are almost fully functioning, except it doesn't disappear when you pick it up, allowing you to get infinite toys. Has no Pip-Boy icon. Regular: 140ca2 Broken: 140ca1

Schematics - Rock-It Launcher
Not unused, but the item it's used to craft is. You can find the schematics for this weapon in the hangar at Nellis AFB. They forgot to implement the recipe.

Thrust Control Modules
Duplicate item. 842d7

Vault 22 Mantis Egg
Duplicate item, probably intended for the quest Bleed Me Dry. One is lying around on one of the test maps. ef40d

Currency
The faction-specific currencies have junk item equivalents that are never used.
 * $5 NCR: 13a4d6
 * $20 NCR: 13a4d7
 * $100 NCR: 13a4d8
 * Legion Denarius: 137b9d
 * Legion Aureus: 13a4d9
 * Mangled Denarius: 173236

Keys

 * Red Lucy's Chamber Key: This is a clean key. After completing her associated quest, Red Lucy invites you to her room. At one point, she must have given you the key, or otherwise carried it on her person. 167e18
 * Thorn's Cages Key: This is a worn key. 167e19
 * Thorn' Master Key: This is a worn key. 167e1a
 * Becky Hostetler's Key: This is a clean key. Becky Hostetler is probably the real name of Mrs. Hostetler, the wife of Don Hostetler of the Crimson Caravan Company. There's nothing particularly valuable in her house, so it's uncertain what this would have opened. 167e25

Inaccessible Equipment
Most of these are used in the game, but the player never has access to them.

Inaccessible Armor

 * 1st Recon Assault Armor: Armor resembling the NCR Trooper Armor but in black and red, with 1st Recon patches on both shoulders. It is rewarded to Boone for finishing his second companion quest and telling him to become bloodthirsty. 140c39
 * 1st Recon Survival Armor: The second reward for Boone's companion quest, he can acquire it by telling him to become repentant. It too resembles NCR Trooper Armor but has short sleeves and is a desert tan colour. 140c38
 * Arcade's Lab Coat: 10cda4
 * Aura Token Kicker: This is an odd item. The GECK says it's a pair of sunglasses, but it can't be equipped or even seen if added to inventory. Despite apparently being a Legion-related item (called LegionExplorerAuraToken internally), the only place in the game it can be found is in the inventory of Crandon in North Vegas. 13b1a8 The following developer commentary is in the item's script:
 * Boone's Beret: Not completely inaccessible, but as it is flagged as a quest item and is removed when the quest is completed, the player cannot keep it. Visually identical to the 1st Recon Beret. b7f53

 * Broken Recon Armor: d777a

 * Raul Jumpsuit Armor: Visually identical to Raul's Petro-Chico Jumpsuit but with added reinforcements identical to the Armored Vault 21 Jumpsuit. 15ea6d

 * Slave Backpack: 127c6a
 * Trenchcoat: 11689a
 * Veronica's Armored Robes: This outfit resembles the Oasis robe from Fallout 3 but without the branches. It is in the possession of companion Veronica. 14823e
