Shock Treatment

A work crew from Prodromos has a dangerous plan to try and control the Remnant. They should be stopped before someone is injured. Search Prodromos for clues to where the work crew has gone.

Acquisition
There is a terminal inside the building next to the Research Station in Prodromos. Reading the message left there will activate the mission.

Find the work rosters
On the second floor of a building where Cain Fawkes, the chief engineer, is standing, there is a datapad with the work rosters.

Ryder recognizes the name Jennings from the terminal's message. However, there are too many possible locations for Jennings to be found at; they must be narrowed down.

Investigate medbay
Scanning the medical equipment next to Dr. Ramirez, SAM finds that wounds caused by Remnant were treated here. Tracking the sand particles extracted from the wounds, he is able to deduce that they originated near a monolith.

Investigate the monolith site
Head to the monolith near Prodromos. The work crew isn't there, although a piece of communications equipment has been left behind. Scan it to listen to a brief conversation between members of the crew, revealing that they are near the Four Giants.

Get to the work crew
Once the conversation is over, a timer begins; you have a little over 2 minutes to reach the crew, so get in the Nomad and drive to the quest marker at a Remnant structure east of the Four Giants. You find the crew being attacked by Remnant, including a Nullifier.

Speak to the survivors
With the Remnant eliminated, speak to the Initiative survivor, Jennings. Regardless of dialogue option, he is talked down from his attempts to control the Remnant, and the mission is complete.
