Solid Snake's parachuting companions

During the Outer Heaven Uprising, Solid Snake and three other companions perform an air insertion into the jungles of Outer Heaven, by parachuting from a transport plane. They landed separately and Snake infiltrated the main fortress alone.

Behind the scenes
The Nintendo Entertainment System version of Metal Gear features a different opening sequence to the original MSX2 version, in which Snake is not the sole infiltrator into enemy territory. Although Snake later receives assistance from three resistance members (Schneider, Diane and Jennifer), no connection between them and the three parachuting companions is ever established.
