Broken Mirror is the second expansion pack to be releases for WARHAWK. It features a new map, Vaporfield Glacier, and the APC (Armored Personnel Carrier). A description of Broken Mirror, along with relevant screenshots, can be found here at Sony's playstation.com blog.
Vaporfield Glacier is the first map to include precipitation of any form, which varies across the map. Some aries experience minor flurries, while other are sub-blizzard.
