Great package of songs, even if you've never played the game. Several are a mix of dark environmental music with heavy emphasis on resonant noises that sound fantastic in headphones. Others, such as "Mortal Kosmic" have a nice technometal base with grim undertones. These tunes would be right at home in the back alleyway of a run-down club, and I reccomend you check 'em out if you're into game music that gets grimdark without slathering on eyeliner and sparkles. Archive is well named, with only a few of the more ambient tracks lacking a proper title.
