Alternative Atmosphere: Ambience Overhaul (GMod version)

Intended to be paired with Extended Environment
Original HL2 Version

A horror focused redux of the majority of environmental & ambient sound effects in HL2 (and some stuff from the episodes) for a more liminal feel. Completed with a variety of sources, such as:

Some replacements already out there just weren't doing it for me. I wanted a best of all worlds from the sound design of grungy 2000s horror & scifi games, and later down the line games with higher quality ambience. It's about as close as I could get to making the ambience feel like DOOM 3 and S.T.A.L.K.E.R.'s; you'll be hearing some weird noises here and there.


Most credits go to the original sound designers, Mellish for ripping stuff from Dead Space, and Yoru for inspiration. I simply edited and revised everything for replacements I deemed fit.

I know the addon is nearing like 800 mb now, but that's because nearly every sound (from HL2, HL2's Episodes, and CS:S) is being accounted for and replaced.
If you are getting icky icky no good screeching sounds delete the sound cache in the game's directory & the addon's directory.
