I got a bunch from the same old game I love:
Sample 1 (https://youtu.be/dRAQriBROcw)
Sample 2 (https://youtu.be/zGQAYpolb3Q)
Sample 3 (https://youtu.be/_n72Xwx4YM4)
Sample 4 (https://youtu.be/2chnmlXtJjs)
Sample 5 (https://youtu.be/g8SDTNXCfhI)
These two take the win for me:
MNOG OST - Telescope Ambience (https://youtu.be/0PqJpA5nM4A)
MNOG OST - Beach Chant (https://youtu.be/VMNrPCEqVkc)
This game probably had the best soundtrack I've ever heard of for such a strange theme, mixing in tribal with technologically advanced elements. I don't think they're exactly creepy, but it's definitely haunting. Especially if you're one who's attached to the game itself.
Oh look, a bonus (https://youtu.be/m1yzm1bSlVs)
