This is the background music/soundscape i did for a long endured half life 2 level i did a while back,
a roadside lumbermill and town is decimated by a dam break and much of it is in 5 feet of water, the unusually large car garage is pitch black in most spots but the cameras can pick up the unusual visitors walking about on the bottom story,

one actually gets the idea to take the elevator up to you while your sifting about through the abandoned offices upstairs.

by the time the elevator stops at your floor, theres nobody in it, the power finally gives out, and its just you, blackness, a lot of droning pipes and ten stories below all is quiet.
i think i got sidetracked with WOW...

but this track freaked my pal tyler out pretty good testing the level, so i hope your lights are out too.
