Last page there's a link to an entire audio Q and A http://www.gamesradar.com/f/grand-theft-auto-iv-audio-qa/a-20080418152838249060guise said:Have I just missed it or has anything been said about the game's use/quality (or lack) of 5.1 audio?
No game on these 2 systems comes with anything less than 5.1. About Euphoria, it's not only for special situations, it starts the moment there's a impact. Example: after someone is shot, getting hit by a car, falling down, things like grabbing on to a chopper.
