Clear Sins base with the Duty group.

 is a storyline 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.

"Good, right on time Major. We already know about the situation. Our military sources have confirmed that Sin's base is deep in the mines. Our strike team is ready to get rid of these bastards once and for all! We can't allow anyone to trifle with Duty! We are the strength, law and order in this cesspool! I marked on your minimap the position where we will start our assault. Let's get to work! See you soon, Marked One."

Overview

 * This is a pretty straightforward camp elimination and the player will have superiour weaponry and armour at this stage.
 * Previous knowledge of the Mines geography is a distinct advantage. This will be a likelihood if the player has played a more orthodox (non-Duty) storyline mission-chain previously.
 * Completion spawns the concluding mission segment: Find the disc with intelligence information prior to a mission debriefing with Voronin.

Trivia

 * There is the opportunity to liberate a Vintar BC from Veles' corpse.
