Fallout: New Vegas Reputation

Overview
Reputation in Fallout: New Vegas is a way to measure general feeling for your character in each principal towns and factions like Fallout 2, and will even give you access to new areas in the game.

Reputation can be modified by doing good or bad deeds, like completing quests or killing townsfolk or member of a faction. Your reputation with any given group is a measure of the combined total of Fame and Infamy that you have earned. The benefits and drawbacks of any given reputation depend of the group itself. You may receive discounts with merchants, provoke attacks from hired thugs, or simply be treated differently.

You can also equip faction clothing (e.g. NCR uniform) to impersonate a member of the faction the clothing belongs to, and will be considered one of them, meaning your reputation with the respective faction will be "neutral", regardless of their actual disposition towards you (i.e. a "vilified" reputation will turn into "neutral", as will an "Idolized" reputation, with all drawbacks a lower reputation brings!). Note that such a disguise will only work on common members of that faction and that officers, security guards and dogs will be able to see through it. Also, any member of a faction with a negative disposition towards the faction whose clothing you wear will attack you on sight as your true reputation with that faction will be ignored as long as you are disguised.

Reputation
There are two different scales of reputation (denoted 1 and 0 in the console), earned by doing helpful or harmful deeds, respectively, to the faction. The combined effects of the two scales result in an overall reputation that is either positive, neutral, or negative. In the table below, these are colored green, black, and red respectively.

Note that at this time there is no known way to erase past deeds except using PC console commands. (However, James Garret can start rumors in Freeside that affect your reputation, just visit the Atomic Wrangler Casino ). Your scores in the two scales only accumulate - neither ever goes down. In other words, while it's possible to move from 'Hated' to 'Sneering Punk', then 'Unpredictable', then 'Dark Hero' by doing more and more good deeds while avoiding bad ones, there is no permanent way to move from 'Hated' back to 'Neutral' or from 'Hated' to 'Idolized.' Similarly, once a reputation of 'Wild Child' is earned, there's no ability to change it at all. However, two specific story events will erase negative reputation you have gained with the NCR or Caesar's Legion when you get to the strip (example - a Smiling Troublemaker will become Liked, since Infamy is set to zero while Fame is unaffected).

When disguised, none of your typical reputation levels apply. This is reflected in the absence of reputations in your PipBoy. However, certain NPCs, particularly guards, may see through your disguise and attack you if you are Vilified with their faction and are standing in close proximity.


 * It is possible to temporarily move from a lower status such as merciful thug, to accepted and up, but only while equipping faction armor. Equip the armor of the faction you are trying to work with to reset your reputation to neutral. Then complete quests and earn fame which will increase from neutral and go up, but only so long as you wear that faction's armor.

Faction reputation
Each faction has a disguise which alters your reputation among other factions.

With the exception of the White Glove Society, Great Khans and Powder Gangers in Vault 19 all factions will attack you with a negative reputation. Additionally, Powder Gangers outside of the New California Republic Correctional Facility and the Powder Ganger Camp South will attack you with a neutral reputation if you get too close to one.

Factions provide the following benefits/consequences with adequate reputation:

Quest scripts themselves rarely grant infamy towards factions, but there are a few which do:
 * Reporting to Colonel Moore or Mr. House that the Omertas have been dealt with in For the Republic, Part 2 or in The House Always Wins, or by completing both Wild Card: Change in Management and Wild Card: Side Bets, will cause infamy with the Legion and turn them hostile.
 * Reporting to Caesar that the White Gloves will or will not ally with him in Render Unto Caesar will cause infamy with the NCR and turn them hostile. Note that the only consequence you will experience from working with Yes Man or House with the NCR is being unable to receive work from Dennis Crocker or Cassandra Moore; your reputation with the NCR will not be affected.
 * Completing Back in Your Own Backyard in any way will result in Legion infamy, although this infamy is not enough to lower your reputation by one level on its own.
 * After completing How Little We Know by siding with Cachino and speaking to Caesar, you will be warned that further crimes against the Legion warrant death. Completing Restoring Hope, Oh My Papa by breaking up the Legion alliance, or I Put a Spell on You by siding with the NCR and speaking to Caesar after this warning OR speaking to Caesar again after failing to confess all crimes will result in Legion infamy and the Legion permanently going hostile. Note that certain scripts, such as Caesar's dialogue on House's death, will override his 'warning' dialogues.
 * Activating the self-destruct sequence in Hidden Valley gives you 100 infamy points with the Brotherhood.
 * Completing Ghost Town Gunfight will always grant enough Powder Ganger infamy to lower your reputation by one level. Killing any Powder Gangers during the quest will further increase your infamy.
 * Completing Beyond the Beef by tattling on the White Glove Society to Heck Gunderson results in White Glove infamy.
 * Telling Marjorie that you "eat people, too" will result in the White Glove Society infamy.

Towns reputation
A town's reputation determines your treatment by the townsfolk. Unlike factions, you cannot alter a town's reputation with faction armor. Towns will never be permanently hostile to the player; leaving the town for three days and returning should remove any hostility. Note: Script for Primm reputation exists within the game, but is not used. A mod exists for PC users to activate Primm reputation.

A positive reputation may yield positive dialogue, discounts from vendors, and even free gifts from wandering citizens. A negative reputation may result in negative attitudes by the citizens and higher prices when trading.

Specific consequences of reputation within towns include:

Scripted instances of town infamy include:
 * Lying to Lindsay about Mr. Cuddles results in Boomers infamy, regardless of whether you pass the Speech check.
 * Walking off during Pete's story in the Nellis Boomer Museum or condescendingly responding to his answers to your questions will result in Boomers infamy.
 * Completing Run Goodsprings Run will always lower your Reputation by one level in Goodsprings; killing townsfolk yourself results in further infamy.
 * Completing Beyond the Beef in a way which results in Heck Gunderson blockading food to the Strip will result in Strip infamy. Generally, this infamy would be garnered by tattling on the White Gloves and failing to pass the following Speech check.
 * Completing How Little We Know by siding with Big Sal will lower your Strip reputation by one level.

Bugs

 * It is possible that the game doesn't register taking off faction armor properly when switching directly to another piece of armor. In that case your PipBoy will still show your reputations as if you were wearing faction armor. This may lead to confusion when the player is being attacked by previously friendly factions. Putting on any kind of faction armor and taking it off again usually restores the players faction standing. Even if it gives you the message, "You are no longer dressed as a member of..." when removing faction armor it may not register correctly.


 * There is another bug that makes it when you equip a faction armor and take it off will reset that faction's reputation. This can be good in some cases, such as if you are vilified with the Powder Gangers and then equip and remove their armor then they will be neutral again. However, faction benefits, like the NCR Emergency Radio or McCarran monorail WILL be permanently lost. This can be very frustrating for players, as the reset seems it's not permanent. If you have completed all available side missions for the NCR or Legion, you cannot regain your reputation.


 * If the game manages to load a Powder Ganger while the player character has neutral or negative reputation, then that NPC will permanently remain hostile, even if they respawn and the player character later gains positive reputation. Additionally, the Powder Gangers at Whittaker Farmstead will be hostile regardless of your Powder Ganger reputation; however, killing them does not seem to affect your reputation.


 * A Negative Reputation With the NCR -- They give you 3 days to remove your negative status. If you wait 24 hours in the same spot after they've warned you, interacting in dialogue with them each day, you may find their dead bodies randomly in front of you when judgement day comes. How they were killed is unknown.


 * A Negative Reputation With the NCR -- NCR Rangers have been spotted inside Vault 34 during the quest "Et Tumor, Brute?" possibly attempting to warn you about your bad reputation (or killing you). They'll engage in a battle with the Feral Ghouls of the vault before attempting to interact with you.


 * Encountered a bug where Legion were hostile no matter what even though reputation with them was either liked or idolized. DID NOT have Boone as a companion or even have him recruited, nor was any faction armor worn. Work around: thankfully this reset after completing Ring-a-Ding-Ding!, although dogs sometimes still turn hostile for no reason forcing the player to sneak attack them when this happens to maintain reputation. This may have been possibly caused by previously wearing another faction's armor and upon removing it the disguise was not properly removed which is another known bug.
