Sergei Gurlukovich was born and raised in Snezhinsk, formerly known as Chelyabinsk-70. Former Head of Spetznaz. Col. Sergei Gurlukovich became the leader of the Gurlukovich Mercenaries, a heavily armed group of Russian militia. During the Cold War, Sergei served in Spetsnaz and worked within GRU where he met Revolver Ocelot.
Hungry for the power that Metal Gear REX would offer him, Gurlukovich gave a Hind-D gunship to Liquid as a down payment for data on the REX project. Liquid however, disliked Gurlukovich, calling him more of a politician than a warrior. In addition, Liquid arranged for Gurlukovich's troops to ally themselves with the Genome Army, but this plan was ruined when Solid Snake destroyed REX. In essence, it is probable that the alliance would have never even lasted long if it really occured since Liquid and Sergei had very different aims.
Two years later, Gurlukovich heard word about a new Metal Gear being scheduled for transport via the Hudson River.His troops later seized the oil tanker which was transporting the Metal Gear, with Gurlukovich personally joining the mission along with his daughter Olga and Ocelot.
Gurlukovich appears in the last holds with Metal Gear RAY inside though is surprised to find out that Ocelot had different intentions with RAY, much to Sergei's anger. After noticing Ocelot's true allegiance, Sergei attempts to shoot Ocelot though in the end, he is the one who is shot along with Marine Commander Scott Dolph. He then dies with his men as RAY proceeds to destroy the tanker and the futile resistance the Marines could offer.
