Find the Gold Fish artifact

 is an optional side-mission featured in S.T.A.L.K.E.R.: Lost Alpha. "It's not a very expensive artifact though I want to figure out how it protects living creatures from weapons. Strange, isn't it?"

- Sakharov

Overview

 * The side missions in Lost Alpha are largely symbolic, reward the player far more frugally than in the base game, and detract from the game generally. Why would a player hunt down and recover a body part and off load it for a pittance?
 * This is the third such mission given by Sakharov and completion is required for progression to the other (poorly rewarding) missions.

Trivia

 * The actual artefact could be lying around near the various anomaly clusters on the Yantar level, but these spawns are fixed at the beginning of the game and may not be reliable.
 * One anomaly field in the Dark Valley is scripted to spawn this artifact occasionally.
 * Another may be found in the Music Village.
