- PDA contact biography
- Located at the Pig Farm in the south-west corner of Dark Valley.
- Gives the player information during the main mission line on how to enter the Bandit Base.
S.T.A.L.K.E.R.: Lost Alpha:
- The player must meet him in order to infiltrate the Bandit Base for the main mission line.
- Missions given in Lost Alpha:
S.T.A.L.K.E.R.: Shadow of Chernobyl:
- Plays a completely different role and simply wanders around in numerous maps in the Zone.
- Despite the resumé and a tendency to wander around the Zone in S.T.A.L.K.E.R.: Shadow of Chernobyl, in the Lost Alpha this NPC stays firmly rooted to one spot in the Pig Farm in Dark Valley.
- Carries the unique weapon Sniper Obokan.
- Killing him to acquire it would be somewhat idiotic, and lugging a Fuel barrel from the Bar to place outside behind him might work, but is tedious and will probably get the (unrepairable) weapon damaged in the process.
- It is possible to draw helicopter fire onto his position later on, but this is also difficult and more likely to result in the player getting shot anyway.
- His only current purpose (patch 1.3003) is to brief the player regarding the infiltration of the Bandit Base and the Monolith Base in the area.
