For six years, Germany's mountain troops provided rapid mobility in rough terrain where the panzers could not operate. Gebirgsjäger fought in the Carpathians, Greece, the Caucasus, Norway, Italy and on the Arctic tundra. Eventually seven divisions of elite Army mountain troops and three of very poor Waffen SS troops would be formed.

Edelweiss Expanded Edition is a Panzer Grenadier supplement adding German regular army and Waffen SS mountain troops to the game series. It is not playable by itself, but requires ownership of Eastern Front to play most of the scenarios, and Road to Berlin, Battle of the Bulge, Desert Rats and Afrika Korps to play all of them.

It's a revised version of the original Edelweiss supplement released in 2002, the second supplement to the Panzer Grenadier system. All of the previous 24 scenarios have been thoroughly revised to take advantage of map boards and playing pieces not available then, and with five more years of design experience and player feedback. And there are eight new scenarios as well. Scenarios take place on all fronts, with most of the fighting taking place on the Eastern Front but now extending to 1945. Each scenario has its own card in a spiral-bound booklet, just like the popular Iron Curtain and North Wind.
