Weather effects are the only real additions in the area of graphics. These effects also go a long way towards adding a much deeper and more dangerous atmosphere to the game. Rain, snow and sandstorms show up in nearly every level, as does fog and dust that cuts down on visibility. As a result, missions are a little trickier and take just a little more planning than in previous games. Other than the added atmosphere, everything else looks more or less the same as before, which isn't that much of a letdown considering that the series has always managed to rank among the Xboxís best.
Sound is much of the same; everything you remember from the Ghost Recon 2 is here. The only real changes to the format are a few new lines of dialogue. Your team is a little more talkative this time, especially after making a kill -- prompting a short cheer or brag. Music is, as always, a non-issue. During gameplay, the only "music" you're likely to hear is the buzzing of your squad in your ear and the sound of gunfire (provided you're not using a silenced weapon).
