Frozen Valley 1.1 addon - Dawn of War: Dark Crusade

Based on Warhammer 40,000, deep under the central desert of Kronus, a vast honeycomb of skull-lined tunnels and funeral chambers house the awakening Necron menace. Eons ago, these were the boulevards and squares of a great necropolis built to house the bones of the races who had fallen to the Necrons, and ultimately were where the Necrons themselves retire to spend eternity. Over millions of years, sand and rock had covered it all until ill-fated excavations awoke the deathless.
