    The Alters: Serum or Prosthetic Arm To Jan Miner?

    After a few days of work, the Jan Miner in The Alters will show immediate signs of being an addict, as he constantly asks you to give him painkillers to push out the pain. This sort of behaviour eventually leads him to get involved in a rough accident. This guide will cover whether to craft the Serum or Prosthetic Arm for Jan Miner.

    The Alters: How To Save Jan Miner

    Taking care of the Jan Miner’s needs seems to resolve the problem for our run on The Alters; we didn’t see Jan Miner losing his sanity, leading him to cut off his limb. But if you saw your Jan Miner losing his arm, you must save him as quickly as possible. Since his loss of limb will be counted as a Heavily Injured status. Here you will be left with two solutions:

    • Give Miner a Prosthetic Arm
    • Give Miner a Serum (Unlocks Lesson: Vulnerability)

    Saving him requires the addition of four facilities: Workshop, Kitchen, Contemplation Room, and Infirmary. You must also have a Guard or Shrink Alter to tend to the mental needs of your base.

    Option 1: Give Jan Miner a Prosthetic Arm (Inhumane Choice)

    Go to the Research Lab, and research the item Prosthetic Arm (Time: 4:00 hours) for Miner.

    The Jan Scientist will push the idea of a Prosthetic Arm for the Jan Miner to save time, and describe the ordeal as a quick and reliable solution without wasting too much time and Rapidum. This route can be seen as a less compassionate, more corporate overlook of seeing Alters as workers, not as human beings. If thats the play that you are gunning for, the decisions to takethe Prosthetic Arm option will be in line with this.

    After researching the item, head to the Workshop to build the Prosthetic Arm (20x Metal and Mineral). Hand the Jan Miner the Prosthetic Arm to complete the mission. 

    Consequences:

    Talking to Jan Miner after his day of work, he will be happy that he has a metal arm to work with. He will take an emotional hit, as he will only talk about his work even after your compliments, leaving him feeling burdened and less joyful. When you talk to the Jan Technician after the Jan Miner has received his Prosthetic Arm, he will have some rough words for your decision, basically calling out your inhumane treatment, seeing the Alters as clone workers.

    Option 2: Give Jan Miner the Serum (Humane Choice)

    Go to the Research Lab, and research the item Serum for Miner.

    After you had a conversation with Jan Technician about using Rapidum to regrow the arm for Jan Miner, talk to Jan Scientist to learn about the Serum and Research it. Once the research is completed, head to the Kitchen to create the Serum (10x Minerals, x40 Rapidum, x100 Organics).

    Hand the Serum to Jan Miner to help him regrow his new arm. Regrowing the hand through the use of Rapidum seems to be the optimal choice. When it comes to the emotional state of Miner, getting the Serum will make him immediately happy. He will feel grateful to our Jan for treating him and looking after him at the base.

    Consequences:

    Choosing the Serum option also brings in a fair share of consequences. Once Jan Miner gets a new hand, he will work tirelessly, taking on 12-hour shifts even without Crunch Time. Here, assign Jan Miner to the Contemplation room under the supervision of a  Guard or Shrink to help him get control over his mental state. You must send him to the Contemplation room almost every day to help him understand himself, and you will learn the lesson of Vulnerability.
