Another mod that will add new year's beauty to your game is the de_snowcapped map for CSS.
The map is a small Christmas town, which was densely covered with snow.
This location is very atmospheric, as it has a lot of beautiful shops, in the distance you can see the mountains and the funicular. I also want to warn you that playing on this map in counter strike source, you can get hit by a regularly running train, so be careful!
The architecture of the map is somewhat similar to Austria or the Czech Republic.
