From The Vault
Gun Nut is a Fallout 3 Perk.
You are obsessed with using and maintaining a wide variety of conventional firearms. With each rank of the Gun Nut perk, you gain an additional 5 points to the Small Guns and Repair skills.
- Having this perk will allow your character to say they have heard of Reilly's Rangers before, to which Reilly will reply "You're pretty sharp, kid."
- When rescuing Initiate Pek having this will allow you to fix his gun (even though you can do it by having a mediocre small guns or repair skill as well).
- It's possible in the PS3 version (possibly others) that this will not give you 5 points in repair. What causes this to happen is unknown.
- The perk image shows a Missile Launcher among the collection of weapons. The Missile Launcher is actually a Big Gun, and so will not get a bonus from this perk.
