It's now called Winter in Berlin.
It has new terrain shadows, additional lightmaps for some statics (like ammoboxes, and medlockers for example), load screen, menu thumbnail, and a new stereo global ambient sound effect!
The river is also frozen over and you can walk on it!

Oh and it has the nice snow weather effects I made. The primary attraction for this map!

The installer will install BOTH the vanilla BF42 version of the map and DesertCombat version! So those who still love the vanilla BF42 can enjoy this map too!
