Mount Shezna is a snowy, mountainous region located on the northernmost peninsula of Usea, northwest of the port city of Saint Ark. Due to the mountains' high altitudes, Mt. Shezna was the site of several long-range radar stations used to support ISAF operations in the area prior to the start of the Second Usean Continental War.


The region's name is presumably derived from its highest peak, Mount Shezna, which extends several thousand feet above sea level.[citation needed] Due to its high altitudes and northern latitude, Mt. Shezna is known for its extended winters, with heavy snowfall appearing as early as October.[citation needed]

Mt. Shezna is also the site of Krasinsky Crater, one of the many craters left behind by the Ulysses 1994XF04 asteroid. The residual heat from the fragment's impact melted the snow in its surroundings, and as of 2004 water vapor continued to rise from the crater itself.[2]


Main article: Operation White Out

At the onset of the Second Usean Continental War, the Erusian offensive forced ISAF into a full-scale retreat to the east. During the retreat, ISAF abandoned many of its facilities, including the Shenza Radar Station, which fell under Erusian control soon after. Eventually, ISAF was forced to relocate its GHQ to North Point, and the remaining ISAF ground forces gathered at Saint Ark in preparation for their evacuation from the mainland.[1]

In order for the evacuation to proceed as planned, however, the radar facility would need to be eliminated, thereby blinding the Erusians to ISAF's troop movements.[1]

The Shezna Radar Station was divided into two installations: Shezna Radar 1 and 2, located several kilometers apart atop adjoining mountain peaks. ISAF dispatched fighters to destroy the radar stations, allowing the ground forces in Saint Ark to successfully evacuate the mainland and regroup at North Point.[1]
