Fallout 3 DLC


In Runtime
Im running this on a PC of course and I have no idea how to get or where to get the DLC such as the pitt, operation anchorage and broken steel. When I do find it, does it install to its own directory automatically? I've checked google a couple of times but it just lists sites such as Gamespot, gamespy and ign giving reivews on the DLC and how it wasn't working upon release. Thanks!
