Stage: Russia Two MiG 31s, a real-life Russian aircraft, have been taken over and are being used as unmanned bombers. The MiGs attack using fireballs and trails of flaming exhaust. The nickname "Icefox" seems to be a reference to the fictional MiG 31 in the 1982 movie Firefox. The US SNES manual for the game calls the MiGs "Siberiacrafts."
