This map is a snow-ice map with some rivers with one or two snow briges on them. There is plenty of ice on the map, making it harder to build. There are no berry bushes, more sheeps and deers. There is more gold in each pack and more packs. There is a normal amount of stone. There are only small forests, no huge forests, about 7 villagers should take care of one in 10 or 20 minutes. In the water, there are some fishes.
When you start, you start with 3 villagers, 2 ornlu the wolves(in multi-player), a town center and one hussar instead of the usual scout.
There are two versions of the rm, one for single player(blizzard-single) and one for multi-player(blizzard-multi). As I said before the only difference is the wolves because the Ai doesn't use them for attack nor defense, only a few times.
The Ornlu are a very important part of the gameplay(they made a big difference in the game I played yesterday), since they are strong and regenerate their life. You should really use them carefully with monks or in the beginning of the game to destroy an opponent economy if he sent his ornlus to attack someone else.

I played the single-player version of your map as a multi-player game. While I didn't mind the immense amount of ice, it was annoying that some people in the game started with no gold or stone. I suspect this was caused by the placement of the ice. Some players could not build anywhere near their town centers. Unless you're the Huns, it's difficult to do well without room for building houses early in the game...
