Fallout 3 Interview

GameSpy interviews Fallout 3 sound designer Mark Lampert, mostly asking questions about the game's soundtrack.
GameSpy: What real-world weapons did you use to create the sounds of the ones in the game?

Mark Lampert: Quite a bit of the action on the game's small arms (pistols, rifles, shotguns, etc.) is actually recorded from real firearms. A colleague kindly brought two pistols and three rifles over to my place where I could set up a couple of mics and record the sound of the bolt being opened and slammed shut, magazines sliding into place and being taken out, dry firing, etc. The actual sounds of the game's weapons being fired were composited together from field recording libraries, as well a as little bit of Foley recording in places where I might want to add some extra bass or exaggerate the sound of the weapon's action.

Even in the cases of the game's more exotic firepower such as energy-based and custom-built weapons, I still came back to those small arms recordings in order to add different "clanks" and "ka-chunks" here and there. I'm happy to say that the bb gun which the player receives for their tenth birthday was composited together with a mix of two different pellet guns that a couple of other co-workers brought in for me. I was looking for something that sounded sort of cheap and flimsy, and both of these guns were definitely that. Still, anything that can take care of a RadRoach is nothing to sneeze at.
