Fallout: New Vegas Reputation

Overview
Reputation in Fallout: New Vegas is a measurement of how the different factions in the Mojave Wasteland perceive the player character. It is affected by positive and negative deeds that affect the faction in question, such as completing quests or killing members, respectively.

Reputation is separated into two categories: Fame and Infamy. Fame is positive and infamy is negative. Both types of reputation are tracked separately, the combination of which determines one's reputation with any given faction. The benefits and drawbacks of any given reputation depend on the group itself. The player character may receive discounts with merchants, provoke attacks from hired thugs, or simply be treated differently.

Points are accumulated by various means. Completing quests, helping people and generally making oneself useful will result in accumulating positive reputation points. Negative reputation can be earned by killing people affiliated with a given faction or town openly (+30 infamy points each time), being caught stealing (+2 infamy) or (rarely) completing quests for the opposite side. Each action that gains fame or infamy is assigned a set value in the editor, which is added via script:


 * Example: a script that says would result in a very major reputation bump, adding 12 points of fame and instantly promoting the player an entire reputation level.

Fame and infamy
Fame and Infamy (denoted 1 and 0 in the console) are 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.

The ranges of reputation vary by faction. The minimum reputation required for each range are:-

Resetting reputation
There is no way (unless with console commands) to remove reputation points from either scale, except for the NCR and the Legion:
 * visiting Mr House will trigger an invitation to Ambassador Crocker, clearing the negative reputation pool for the NCR,
 * confronting Benny will trigger an invitation to Caesar and clear the negative reputation pool for the Legion.

Beyond that, any positive or negative reputation with a given faction cannot be removed, only offset by a larger Fame or Infamy value. In other words, while it is 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.' And if the player character 'Idolized', they move down the chart to 'Wild Child'. Also, once a reputation of 'Wild Child' is earned, there is no ability to change it at all.

James Garret can be paid to start rumors in Freeside that affect one's reputation with the town. There is a limit to how much this can be done.

Using faction armor, it is possible to gain a higher reputation than would be possible. Equip the armor of the faction the player character is trying to work with to reset reputation to neutral. Then complete quests and earn fame which will increase from neutral and go up, but only so long as one is wearing that faction's armor.


 * For specific low-level range values for various factions, see the Talk Page.

Killing faction members with impunity
Killing members of any faction from a [HIDDEN] state will not cause one to gain infamy as long as the weapon is considered silent and the target dies with one attack, or to use Mister Sandman. The one exception is the Brotherhood of Steel: Only Mister Sandman works, as even silenced weapons and C-4 will cause the Brotherhood to turn hostile.

Faction reputation
Each faction has a disguise which alters one's reputation among other factions.

With the exception of the White Glove Society, Great Khans and Powder Gangers in Vault 19, all factions will attack the player character with a negative reputation. Additionally, Powder Gangers outside of the NCR Correctional Facility and the Powder Ganger camp south would originally attack them even with a neutral reputation if the player character gets too close to one, but this has been corrected in the latest patch to the game.

Factions provide the following benefits/consequences with adequate reputation:

In addition, one's reputation with the major factions affects the kind of Courier duster that is received at the end of Lonesome Road.

Quest scripts themselves rarely grant infamy towards factions, but there are a few which do:
 * Failing Beware the Wrath of Caesar! gains infamy with the Legion and turns them hostile (even if one's overall reputation is neutral (Wild Child). 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, respectively, or by completing both Wild Card: Change in Management and Wild Card: Side Bets, will cause the quest to fail, as will killing enough Legion troops (though this is a moot point since they will be hostile anyway).
 * Failing Don't Tread on the Bear! will gain NCR infamy, the amount and exact consequences depending on how it is failed. 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 (even if one's overall reputation is neutral (Wild Child)). Working with Yes Man or House will fail the quest, but the Infamy gain will be trivial and the NCR will remain friendly. However, all active NCR quests will be immediately failed, and it will be impossible to accept further quests from them.
 * Completing Back in Your Own Backyard in any way will result in Legion infamy, although this infamy is not enough to lower one's reputation by one level on its own.
 * After completing How Little We Know by siding with Cachino and speaking to Caesar, one's 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 the player character 100 infamy points with the Brotherhood.
 * Activating Archimedes I and use it against the NCR troopers in That Lucky Old Sun quest will result in a large amount of NCR infamy.
 * Completing Ghost Town Gunfight will always grant enough Powder Ganger infamy to lower one's reputation by one level. Killing any Powder Gangers during the quest will further increase one's infamy.
 * Completing Beyond the Beef by snitching on the White Glove Society to Heck Gunderson results in White Glove infamy.
 * Telling Marjorie that one "eat people, too" will result in the White Glove Society infamy.
 * Completing Cass's side quest Heartache by the Number by killing Alice McLafferty at the Crimson Caravan Camp site will drastically raise Infamy with the NCR (killing Gloria Van Graff of the Silver Rush weapons shop is required for completing the quest, but will not affect reputation with the NCR. It will, however, cause Van Graff guards to act hostile towards the player character).

Towns reputation
A town's reputation determines the player character's treatment by the townsfolk. Unlike factions, they cannot alter a town's reputation with faction armor. Towns will never be permanently hostile to the player character; 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 Mister Cuddles results in Boomers infamy, regardless of whether one passes the Speech check.
 * Walking off during Pete's story in the Nellis Boomer Museum or condescendingly responding to his answers to the player character's questions will result in Boomers infamy.
 * Completing Run Goodsprings Run will always lower one's Goodsprings Reputation by one level; killing townsfolk results in further infamy.
 * Completing Ghost Town Gunfight will always lower one's Powder Gangers Reputation by one level; killing Powder Gangers 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 one's Strip reputation by one level.

Foreword

 * The reputations are listed below in alphabetic order.
 * Disguises are only available for the five big factions (Brotherhood, Legion, Khans, NCR, and Powder Gangers) and, as such, only mask the standing with those five factions. Other reputations are unaffected.
