Sneering Imperialist provides a 15% damage boost and a 1.25x multiplier to the player character's V.A.T.S. chance-to-hit when attacking members of certain groups, such as tribals, raiders, Fiends, and Great Khans.
Although the perk's description only mentions raiders, junkies, and Zion's various tribals, which non-player characters the perk affects are actually determined by the non-player character's "race" (referring to a game-specific setting rather than perceived racial makeup). This covers a number of groups/factions in their entirety:
In addition, a number of other groups are partially composed of members of the specified race designations:
Finally, a few named non-player characters are covered by this perk:
- The perk opens an additional dialogue option when dealing with Salt-Upon-Wounds, allowing the Courier to encourage Joshua Graham to execute him.
- This perk also grants an additional dialogue option when being spoken to, right after entering Angel cave for the first time, allowing the Courier to be rude to the Dead Horses tribal who directs them to Joshua Graham.
- As opposed to the similar perk Fight the Power!, most "tribal" enemies tend to be weak in the later stages of the game, so the relative merit is more dubious.
- In the image, the Vault Boy appears to be wielding a hunting rifle, and the dead person below him is a Fiend, as shown by the trademark helmet.
- The perk image is similar to that of the Arizona Killer achievement image, except that the Fiend is replaced by President Kimball, and the Vault Boy is wearing a Vault jumpsuit instead of a military outfit and is wielding a hunting shotgun instead of a hunting rifle.
Behind the scenes
- The image and name are a reference to the Age of Imperialism, which involved nations from Europe along with the United States conquering the vast majority of the world during the 19th-century and transforming them into colonies.
- One of the references for Brian Menze was the Sharpe novels by Bernard Cornwell, centered around a British Army soldier serving in the Napoleonic Wars.
- In color, the soldier standing on the dead Fiend is wearing the 19th-century uniform of a British soldier.
-  Joshua Sawyer: "The Sharpe's series was used as one reference for the artist who made the perk icon (Brian Menze)."
