Detailed Walkthrough
Hadrian Sanon has tasked you with getting the Terrmorph sample you recovered analyzed by the best xenobiologist she knows, Dr. Percival Walker, and Commander Tuala has approved the mission. The last Hadrian heard of Walker, he was working with the Trade Authority in Cydonia on Mars, so that's where you'll need to start. Go to Cydonia and visit the Trade Authority - you will need to speak to the manager, Oktai Enbayar, in the back room. Enbayar explains that Walker disappeared after racking up a considerable debt to the Trade Authority due to "discipline issues". He isn't particularly interested in finding Walker, but believes that a group of miners who gather at the Sixth Circle are hiding him.

Upon entering the Sixth Circle, you will be accosted by one of the patrons, Andrew Robillard. As it turns out, the Sixth Circle is a bar reserved almost exclusively for veterans of an old United Colonies military unit, the Red Devils. Either show them Hadrian's genetag, or prove to them that you're with the Vanguard, and they'll be more open to talking to you. The bartender, Lou Saavedra, says that Walker has gone into hiding to avoid having to pay his debt, but that if the debt were settled, he'd be willing to direct you to him. He suggests hacking the Trade Authority's computers to reduce Walker's debt to something more manageable. As you leave, another patron, Cambridge Cooper, approaches you with another possible option - he worked with Walker on finding new pharmaceutical uses for Aqueous Hematite, and believes that the results of that research would be more than enough to settle Walker's debt to the Trade Authority. The only difficult is that the lab is in Mars's Deep Mines, which are overrun with Spacers.

Settling Walker's Debt
At this point, you have three options with which to proceed.

First, you can simply talk to Enbayar and pay Walker's debt in full. The debt is quite large - over 20,000 credits.

Second, you can follow Lou's plan and hack the Trade Authority's computers to reduce the debt. The computers are in an office on the second floor of the Trade Authority, which can be accessed from two doors. The door at the top of the stairs has a Master-level lock, while the other door can be accessed from behind the bar at the Broken Spear, and only has an Expert-level lock. This will reduce the debt to only 500 credits, which Lou is willing to cover you for.

Finally, you can take up Cambridge's offer and head for the Deep Mines. The Mines are extensive and infested with Spacers - you'll need to kill their leader, then contact Cambridge from the lab's intercom. Cambridge will walk you through the process of finishing the research, then direct you to an elevator that will take you up to a back entrance from the mines. Once you have the finished research in hand, return to Cambridge, then take it to Enbayar. You can sell the research in exchange for settling Walker's debt, or alternatively sell it for credits, and use one of the other two methods to settle the debt.

Whichever method you choose, Lou will now be willing to tell you where Walker is - he's hiding out in the old Red Devils HQ. It's no longer accessible from the main entrance, but there is a back entrance through the Deep Mines, for which Lou gives you the key.

Meeting Walker
Head for the Deep Mines. If you assisted Cambridge, the mines will already be clear, and you can take the employee elevator as a shortcut. Otherwise, you will need to fight your way through the Spacers. The key opens the way into a series of massive caverns, which you will need to navigate. Eventually, you will find the HQ, where Walker will greet you at the back entrance.

Deliver the Terrormorph sample, and Walker will take it to a lab station for analysis. He is shocked to discover that the Tau Ceti Terrormorph is not only genetically identical to the Terrormorphs that attacked Londinion, but that it shows no signs of having been transported. It simply appeared in a time and place that should have been impossible. Concerned about the possibility of another Londinion-scale Terrormorph attack, Walker agrees to meet Hadrian with you. Leave the HQ by the main entrance and return to the Sixth Circle.

Hadrian will lead you and Walker into a back room. Talk to her, and she will reveal that the two of them were both high-ranking UC Xenowarfare experts during the Colony War. During the war, they performed research on potentially weaponizing Terrormorphs, but the project was scrapped. They need the data from the project to get a better understanding of what the Tau Ceti sample means, but Xenowarfare was banned after the war, and the data is securely under lock and key in the Armistice Archives in New Atlantis. To get it, they will need approval not just from the UC Cabinet, but also from the Freestar Collective and House Va'ruun. Hadrian explains that she was able to pull some strings to arrange a meeting with the Cabinet, and asks you to meet her at the MAST Tower.
