Perilous Underside of the World (слэш)

After Steve becomes an unwilling subject in Ross's pet weapons project to make a next gen super soldier, Bucky is awakened from cryo to join a daring rescue operation to save Steve from an impenetrable government base on the Antarctica coastline. When things go belly up, Steve and Bucky must strike out on their own across the hostile landscape, with Ross's men close behind.
AKA 'The one where Steve throws a snowmobile at a helicopter.'
