The Mojave Wasteland is a harsh place, and who you know—and how they feel about you—can mean the difference between a warm welcome and a hail of bullets. In Fallout: New Vegas, your reputation with its diverse factions and towns is a dynamic, crucial mechanic that shapes every aspect of your journey. This comprehensive Fallout New Vegas Steam reputation system guide will break down how fame and infamy work, how to manage your standing, and what consequences your actions truly carry.

Understanding Fame and Infamy

Unlike previous Fallout titles, Fallout: New Vegas employs a dual reputation system: Fame and Infamy. These two factors are tracked independently for each faction and town, rather than on a single opposing scale. This means you can be both famous and infamous with the same group, creating unique and often complex interactions.

  • Fame: Represents positive actions and goodwill. Gaining fame typically comes from completing quests for a faction, helping their members, or making choices that benefit them.
  • Infamy: Represents negative actions and hostility. Infamy is usually acquired by killing faction members, failing quests in a way that harms them, or making choices that go against their interests.

Your overall standing with a group, whether it's the NCR, Caesar's Legion, or a small town like Goodsprings, is a combination of your accumulated Fame and Infamy points. The specific thresholds for different reputation levels (e.g., Neutral, Accepted, Liked, Idolized, or Shunned, Hated, Vilified) vary significantly between groups. For instance, becoming 'Idolized' by Goodsprings might only require about 15 Fame points with low Infamy, while the NCR demands a minimum of 80 Fame points.

Earning and Losing Reputation

Every decision and action you take in the Mojave can influence your standing.

Questing and Choices

The primary way to gain Fame is by successfully completing quests for a faction. Talking to specific individuals or making certain dialogue choices can also contribute. Conversely, failing quests, especially those with significant consequences, or actively working against a faction's goals can lead to Infamy. These points, once gained, are generally permanent and will stick with you throughout your playthrough, except in a few rare instances.

Consequences of Your Actions

A good reputation can unlock unique dialogue options, access to special vendors, discounted prices, or even assistance in combat. Some quests might even require a certain level of Fame to initiate. On the flip side, high Infamy will often result in being attacked on sight, denied access to certain areas, or even having hit squads sent after you.

Town reputations, however, function slightly differently from major factions. While negative actions might temporarily turn townspeople hostile, they usually won't remain permanently aggressive. Spending some time away from the area often resets their immediate hostility, though your underlying Infamy with them will persist.

The Power of Disguises

One of the most tactical elements of the Fallout: New Vegas reputation system is the use of faction disguises. By equipping specific faction armor, you can temporarily mask your true reputation with that group.

Strategic Disguises: A Temporary Neutrality

Wearing a faction's armor sets your reputation with them to neutral, allowing you to access areas or complete quests you otherwise couldn't. However, this neutrality is fragile; observant NPCs like lieutenants, security guards, or even trained dogs can see through your disguise, potentially turning the entire area hostile.

When disguised, you also temporarily adopt the relations of that faction with other groups. For example, if you're wearing NCR armor, Caesar's Legion members will treat you as hostile, even if your personal reputation with the Legion was previously positive. While disguised, any Fame or Infamy you earn will still be added to your true, underlying reputation once you remove the outfit. This allows for clever maneuvering, like completing quests for a faction you're normally vilified by.

Managing Your Infamy (and Rare Resets)

Given that reputation points are largely permanent, Infamy can be a heavy burden. However, there are a few rare exceptions where you can mitigate your negative standing:

  • Major Faction Opportunities: At specific points in the main storyline, both the NCR and Caesar's Legion may offer you a one-time chance to reset your Infamy with them. These are critical choices with significant narrative implications.
  • Freeside Rumors: For the Freeside area, you can pay James Garret at the Atomic Wrangler casino to spread rumors. This service can either increase your Fame or reduce your Infamy within Freeside.

These opportunities are limited, reinforcing the weight of your choices in the Mojave.

Advanced Reputation Control (PC Console Commands)

For PC players on Steam, if you wish to directly modify your reputation, Fallout: New Vegas offers console commands. This can be useful for role-playing specific scenarios, fixing unintended reputation glitches, or simply experimenting with different faction standings.

According to community reports and guides found on platforms like Steam Community, the primary command is setreputation <ID> &lt;0/1> <reputation>.

  • <ID>: This is the unique identifier for the faction or group you want to modify.
  • &lt;0/1>: Use 0 to affect Infamy, or 1 to affect Fame.
  • <reputation>: A number between 0 and 100. 0 removes all reputation (either positive or negative), while 100 sets it to the highest possible level (Idolized for Fame, Vilified for Infamy). Note that intermediate reputation titles (e.g., Accepted, Liked) may not correspond directly to specific numbers and might require in-game testing.

For example, to become idolized by Caesar's Legion, you would type: setreputation 000f43dd 1 100.

To remove all negative reputation with a faction, you would use: setreputation <ID> 0 0. To remove all positive reputation: setreputation <ID> 1 0.

You can verify changes by checking the General tab under Stats in your Pip-Boy. Be cautious when using console commands, as they can sometimes lead to unforeseen issues or break quest progression.

Frequently Asked Questions

How does the Fallout New Vegas Steam reputation system differ from other Fallout games?

Unlike Fallout 3's Karma system, New Vegas uses separate Fame and Infamy meters for each faction and town. This allows for more nuanced relationships, where you can be both positively and negatively recognized by the same group, without one canceling out the other.

Can I reset my infamy with all factions?

No, opportunities to completely reset Infamy are very rare and typically limited to major factions like the NCR and Caesar's Legion, occurring at specific points in the main story. For Freeside, James Garret can reduce your Infamy. Most other Infamy is permanent.

What are the benefits of high fame with a faction?

High fame can grant you access to unique faction quests, special vendors with exclusive items, discounted prices, safe passage through their territories, and even backup in combat. Being 'Idolized' often represents the peak of these benefits.

Do disguises completely protect me from reputation consequences?

While faction disguises offer temporary neutrality and allow you to navigate hostile territories or complete quests, they are not foolproof. Certain perceptive NPCs, such as faction leaders, security guards, or even trained dogs, can see through your disguise, potentially turning the entire area hostile.
