Inspired and built upon Grimples' Ambient Sound mod and llunak's Ambience Forest mod, adding background sounds for all tilesets (including alienbase, finalmission and xenonautbase). Removed out of place/bad quality sounds, changed the soundscape to be more unique for each tileset and added even more new ambient sounds. Examples include:

• cold winds on arctic and tundra maps
• farm animals on farm maps
• crickets, owls, wolves and coyote sounds at night
• eerie noises on alienbase maps
• alarm sound and computer noises on xenonautbase maps
• crowd panic, battle noises, air raid sirens and more on terror missions (town and soviettown)
  

NOTE: Disable Grimples' Ambient Sound mod and llunak's Ambience Forest mod before using (if on an existing save to avoid problems, rename or remove the sounds_gc.xml file to -sounds_gc.xml for example in the respective folders for those two mods).

DISCLAIMER: It has been discovered that the ambient sound system of X:CE bugs the save system for some people and can cause crashing when loading or finishing a Ground Combat mission. There is a work around which is to:

ALWAYS LOAD A SAVE THAT IS ON THE GEOSCAPE FROM THE MAIN MENU AND THEN NEVER TOUCH THE LOAD SYSTEM FOR THE REST OF THE SESSION

If you don't experience any crashing you can use the load system like normal, but if you do please be aware of this issue when using this mod.

- Requires X:CE 0.34.2 -

BIG THANKS TO llunak for implementing this feature and Grimples for making the first major sound mod that inspired me to make this.
