Maps
Microsoft was nice enough to provide us with some rendered maps. These basic maps of mountains Milli, Bear, Breck, and Hood will hopefully help you get a bit of a handle on the different drops zones as well as some of the gap and snowmen locations. To our knowledge, the maps Microsoft provided are accurate to the final product.
