Gurlugon

Gurlugon is a giant soldier created inside a virtual reality construct.

Substance
Gurlugons appear in Variety missions where Snake or Raiden have to sneak to the end of a stage without being seen. In these scenarios, the Soliton radar is disabled, forcing the player to sneak past them by using their head position as a point of reference to their field of vision.

At the end of Raiden's Survival mission, he has to do battle with a Gurlugon by destroying it piece by piece.

Alternatively, Raiden can use two items to end the battle quickly:
 * Lay down a Book in Gurlugon's light of sight.
 * Equip the BDU and the AKS-74U.
