Fallout 3

Fallout 3 is 2008's award-winning post-apocalyptic corpse-lootin' dungeon crawler. The game's dedicated mod kit (G.E.C.K.) can be used to easily view much of this unimplemented content.

Unused Quests

 * 14e90 MQ10 Infiltration: Unused stage of the main quest between "The American Dream" and "Take It Back!".
 * 14e92 MQ12 Last Rites: Unused stage of the main quest set after "Take It Back!". It has no objectives remaining in code. Most likely it is the basis of the Broken Steel DLC.

Lea appears to be a previous name for Moria Brown, as can be identified by Script notes for her dialog lines.
 * 14e96 MS03 Wasteland Survival Guide: Unused stages of the optional quest, where the player would print something at Hubris Comics, but not required for the quest.

Throwing Skill
Throwing is a skill from Fallout 1 and 2, which in 3 was consolidated into the Explosives skill to simplify gameplay. There are Pip-Boy images in the game's texture file which reveal that it was planned to return at some point before ultimately being cut.

The image intended for use as its skill icon was later used in Fallout: New Vegas for the Heave Ho! perk.

Actor Effects
These are bestowed on actors (including players), mostly through perks.
 * Atomization: This is an unused critical kill effect for weapons that fire mini-nukes, much like disintegration or gooification. 5b141
 * Better Rivet City Prices: Related to the quest 'Wasteland Survival Guide'. Increases barter by 15, regardless of location. 6f592
 * EMP Disable: Has the effect of a Pulse grenade on susceptible targets. The weapons in-game use the EMP object effect, which is effectively the same thing. 5b148
 * Kamikaze: A trait from Fallout 1 and 2. 3 doesn't have traits, so it would have been a perk instead. Increases AP by 10 and reduces DR by 20. 94ec3
 * Live Giver: There are effects for unused second and third ranks for this perk. Rank 2: 31d8a Rank 3: 31d8b
 * Poison: Called "DeathClawPoison" internally. Deathclaws cannot inflict poison. 6b20e
 * Rad Poisoning: Called "NukalurkAttack" internally. 9ade8
 * RL3 Survive: Increased DR by 10, three stages. 7d4f2
 * Stealth Shield: Called "EnclaveInfiltratorStealth" internally. Runs a stealth boy script on the actor. 7d412

There are also unused effects for all the bobbleheads, which do the same thing as the items' scripts.

Base Effects
Some of these unused effects show different item bonuses than what is actually used in the game. From the GECK Wiki, "A Base Effect is a fundamental "magic effect" in Fallout 3 that defines a particular way of modifying the player's stats or starting a script whenever the player consumes an Ingestible (food item, drug, or chemical) or is affected by an Actor Effect ("ability") or Object Effect ("enchantment")."

Radio Tenpenny
Alistair Tenpenny's dialog files contain the remnants of a cut radio station. A few of these were re-recorded and added to The Pitt Radio in the Pitt DLC.



Region Differences
The Japanese version had some cuts to avoid getting banned.
 * The Fat Man weapon was renamed to the Nuka Launcher.
 * Mr. Burke was removed from the game, disabling the option to nuke Megaton The Power Of The Atom and beat the quest. It's still possible to complete it by disarming the nuke.
 * Human decapitations are disabled. Ghoul and monster decapitations are unchanged.
