The mission is to defeat the BFF elite arctic sniper unit, Silent Avalanche. The unit is equipped with specialized sniping Normals, and will attempted to jam the player's radar with ECM, and take advantage of the low visibility caused by the environment. This can catch the player off guard, potentially resulting in getting hit repeatedly by Silent Avelanche's sniper cannons. Boosting from cover to cover is an effective means of closing the distance while avoiding the snipers. The mission will end once all enemies are defeated.
