From the Avalanche Press website:
German mountain troops fought on every front except North Africa, compiling an impressive war record (and a few war crimes as well). These elite “mountaineers of the plains” saw action in all sorts of terrain and in all weather.
Edelweiss is a 64-page book supplement for the Panzer Grenadier series, based on the battles fought by German regular army and Waffen SS mountain troops. It is not a complete game: playing pieces and maps are drawn from the following Panzer Grenadier games and supplements: Elsenborn Ridge, 1940 - The Fall of France, Arctic Front, Road to Berlin, Battle of the Bulge, Sinister Forces, Eastern Front, Afrika Korps and Desert Rats. There are 41 (forty-one!) scenarios, each based on an actual battle or situation, plus historical background on the German mountain divisions and their exploits.
Edelweiss includes 161 laser-cut and mounted playing pieces: 157 of them the standard 2/3-inch square pieces of the Panzer Grenadier series, and four of them double-sized monsters. Two are Soviet river monitors, and there are two versions of the giant motorized mortar "Karl."
