DreamStation.cc has written up a fairly negative review of Fallout: Brotherhood of Steel, giving the action RPG an overall score of 4.5/10. Here's a snip about the audio:
The audio and soundtrack is pretty much like the visuals. Gunfire sounds good and convincing. As for people you talk to along the way the voices are clear, but the amount of raw lagauge is uncalled for. After you hear sh** for the 5,000 time when you are in battle it gets old. The soundtrack is pretty non-existent. The game is silent most of the time, but every now and then you hear some heavy metal playing during some big fights. It would have been really nice to have a good soundtrack and less swearing in the game. Fallout: Brotherhood of Steel is a mature game due to the profane language and crudeness of the game.
