Joining Duty is a storyline fork that the player may undertake if certain conditions are met when playing the S.T.A.L.K.E.R.: Lost Alpha standalone mod.

Marked One, Petrenko here. I don't recommend you go deeper into the mines. You pissed off Sin really bad by killing their comrades on escape. Voronin can help you with that if you join Duty, or aternatively go speak to Barkeep, he has a way of easing the situation, for a price of course. Visit one of them as soon as you can before you get yourself killed. While you are still in the area try and get to the lab as originally planned.

Mission AcquisitionEdit

  • The above quote, sent to the player just as the Go deeper into the mines task is about to be executed; indicates to the player that some form of remedial action is necessary in order to proceed.
  • This all comes about if the player wiped out the Sin contingent in the Sin House early in the game.
  • The situation is resolved in one of two manners, as indicated, with the trivial case - talking it over with Barkeep - merely resolving the issue with Sin by paying them off, so that the original task may be executed with the subsequent task chain proceeding as normal.
  • Failing to heed Petrenko's advice will result in the death of the player's actor.
  • Talking the matter over with Voronin results in a Storyline fork being available - Joining Duty.
  • Due to the fact that Voronin will only offer the player this opportunity ONCE, making an interim savegame beforehand is advisable.
  • Both resolutions cost the player 10,000 Ru.
  • Voronin throws in a PSZ 9d Duty armor, counting the "blood money" as an enrollment fee that permits the player to join Duty. Any rapprochement with Sin is now impossible.
  • He then initiates the player into the faction with a semi-pseudo "swearing-in" ceremony:

"I am stately swear to protect my country against the Zone and any stalker which would like to help our goal. I'll never go against the moral code and stop everyone who will join our enemies and support living of this abormination! We are Duty, Zone must be stopped and only we can do it! hurrah!

  • Your new commanding officer then issues a series of missions prior to discharging you from service with the final "Help the yantar scientists", at which point the storyline re-links with the normal storyline task-chain. These are:
Other missions become available and need to be concluded:


  • Although the player is discharged from "active duty" at some stage, which will vary depending upon performance; the player will remain a member of Duty for the rest of the game.
  • This will have various consequences. Freedom will not look kindly upon visitations, and since the only Technician on Outskirts is Skinflint, this may be an inconvenience.
  • Trading with Loners, who may have been "friendly" before the player joined duty will now be neutral at best and the trading returns correspondingly lower.
