MP/Achievements: Should work
There is already a winter season but this mod is worth it to be downloaded. It takes a little different approach where it does not cover everything in snow. Instead it makes it look like the first snow has fallen leaving mud and sand etc visible.
Make a save copy of the original TextureCache zip file. And then overwrite the original with the one in this mod. Place the media.xml inside the Media folder. The media.xml is borrowed from the Winter Season mod because originaly the First Snow mod does not modify the GUI making it hard to see it when driving.
