this feels like an horror movie would something use as their sound effects are atmospheric

I use it myself, it works pretty good

I'm curious, anyone know if this goes well with prop ambience?

I would test it myself but at the time of typing this I'm not in a position to really try it out.

not a hard requirement, it's in the description

Could this be incompatible with "Insurgency Physics" sound mod? That one is old but I really like the impact sounds and some of the sounds from that mod. Haven't tested it yet to find out if they can mix and overlap each other.

Is this a hard requirement for Alternative Atmosphere?

i really like this, feels really immersive on horror maps. or just ones the feel unsettling. btw whats the animation pack you're using in the video, I've been trying to find one like it but idk what the name of it is.

This already uses a lot of assets from Black Mesa so it would be pointless

Can you port this to Black Mesa, please and thank you.

I love these sounds keep up the great work
