    This achievement depends on your choice before chapter 4 "Prison".

    This depends on your choice while talking to the the psychiatrist prior this mission - if you refused the medication, you have to kill everyone in the prison. The dossier will say something like "KILL KILL KILL KILL ...".
    If you did take the medication like usual, you have to complete the prison stealthy without killing anyone.

    The Achievement will unlock, once you pick up the Prototype Key infront of your apartment, after completing the level. (Thanks for the comment!)

    BreakerShadowAh! Thank you for the advice with the key, I'll add that to the solution!
    And yes, like I wrote it: If you refuse the medication in the talk with the psychiatrist your goal for Chapter 4 is to kill everybody. Also your dossier will only say something like "KILL KILL KILL KILL ... "

    BreakerShadowI was rude every time the psychiatrist wanted something from me.. hang up on the phone a lot of times, also interupted every of his speech and talked to the DJ. After that you can refuse the medication, while he tries to talk to you.

    If you unlocked the REFUSED MEDICATION achievement you kill all of the guards in the prison. If you did not unlock the achievement you have to spare all the guards. When you return to your apartment building there will be a brief case waiting on you with the PROTOTYPE KEY inside.
