Find Greben's stolen stuff

 is a storyline side mission appearing in the S.T.A.L.K.E.R.: Lost Alpha mod and will only be given if the player has joined Duty.

"When these bastards attacked our position, they not only sprayed us with lead, but those buggers stole my favourite guitar!! Bastards, I can't forgive them for that. We also had a case of some stuff to..you know...make the days easier...if you understand what I mean! Bastards from the gas station group took it! Can you try to find these things in their respective camps, please?"

- Greben

Overview
The mission splits into two parts:
 * 1) Find Greben's favourite guitar and stolen case.
 * 2) Talk with Greben.
 * The mission is not given until the player accepts Greben's Eliminate bandits camps mission, and neither item spawns until the given camp is actually eliminated.
 * Both missions may therefore run concurrently.

1. Find Greben's favourite guitar and stolen case.

 * Because this mission includes both items, it is impossible to complete unless player obtains both of the items. Mission ties in with the other, separate mission; Eliminate bandits camps which involves cleaning up two separate bandit camps in Yantar.
 * The guitar location is in the Bandit Village, west of Duty Boathouse, while the drug case, it in the Motor Pool.

a. Guitar

 * After player kills all the bandits in village, he/she must then find the guitar.
 * If the player is using patch 1.3002 or 1.3003, it can be found inside the perimeter of a ruined house infested with anomalies, leaning against a wall.
 * Can sometimes be difficult to spot, especially in night conditions or if the player tries to hurry.
 * House ruin is on the north-west corner of the village.

b. Drugs

 * The Motor Pool is located at the entrance of the level from Bar-Rostok. It is populated with six bandits, and after the player completes the slaughter, the drug case needs to be located under one of the tanker trucks.
 * The world model is the same as the Artifact Merger, possibly a placeholder until new patch.

2. Talk with Greben.

 * When the player discusses the mission result with Greben, he expresses gratitude of course.
 * He also claims to turn over to player something "found in an anomaly" but the item may not appear in player's inventory and there is no message blurb in the dialogue to say that any item was received.

Trivia

 * Interesting to think, why Duty fighters who oppose all things Freedom  members do should need the drugs. Ordinary, one would normally assume that Duty do not like drugs.
