Incapacitate Dahl

Incapacitate Dahl is a side quest in Prey (2017).

Overview
Igwe contacted me after Commander Dahl arrived on Talos I to propose an alternate way of dealing with Dahl. Igwe wants me to incapacitate him - not kill him. Removing Dahl's more recent Neuromods will make Dahl forget his orders to infiltrate Talos I, but keep his knowledge of how to pilot the shuttle home. Maybe he can fly us home.

Objectives

 * Meet Igwe at your office.
 * Subdue Dahl without killing him.
 * Wait for further instructions from Dr. Igwe.
 * Activate the Neuromod removal process.

Walkthrough
Assuming you completed Doctor Igwe and saved him during Shipping and Receiving, Dr. Igwe will call you after Dahl’s arrival with a plan. You just have to incapacitate Dahl without killing him. But you’ll have to find him first.

He’s down in Life Support in the Oxygen Flow Control Room, which is on the right side of the Atmosphere Control Room. (You’ll be on the other side of Atmosphere Control during Missing Engineer optional objective.) With your tracking bracelet deactivated, he won’t see you coming. Just draw your Disruptor Stun Gun and drop him. This will let you completely skip over Dahl Ultimatum.

Activate the Neuromod Removal Process
If Dahl survives his encounter with you during his ultimatum or when you incapacitating him, Dr. Igwe will retrieve him and take him to Neuromod Division. You’ll get another call from Dr. Igwe asking you to meet him in the Neuromod Insertion Room.

The Neuromod Insertion Room is on the second floor of the Neuromod Division. You may have been up here before to explore the Volunteer Quarters and the Simulation Debriefing Room. When you meet up with Dr. Igwe and the unconscious Dahl, everything is prepped. All that’s left if for you to push the button(s).

Go to the computer next to the chamber. You’ll have to hit a series of buttons here. On the Surgical Procedures menu, press Engage Surgical Harness. Then switch to Neural Scan, and hit Preform Neural Scan. Now you can switch back to Surgical Procedures to choose Perform Neurotomy. (You can play and stop the debriefing as much as you want, but it doesn’t affect anything.)

After you and Igwe have handled Dahl, the Incapacitate Dahl objective will go on hold until you complete The Repo Man.
