The Mystery Augs

SM03: The Mystery Augs is a side mission in Deus Ex: Mankind Divided. It is available for Adam Jensen to start during his first visit to Prague and spans over all three visits. Unlike all other side missions in the game, this one does not have an achievement/trophy associated with it.

Confront Sarif in my Apartment
After you complete Getting in Top Shape Again, Adam will decide he needs to have a chat with David Sarif to see where the mystery augs came from, so make your way back to Adam's apartment and use the remote control to call him up (assuming you already talked to him before you went to see Koller, otherwise you may need to open the blinds in the bedroom to get Sarif's number). Sarif is adamant that he never had hidden augments put into Adam, and when Adam reveals the neodymium shield, Sarif recognizes it as a TITAN aug developed by someone Megan Reed and himself once interviewed, Vadim Orlov, but turned him away because Orlov did not like people questioning his choices. Sarif will then take it upon himself to track down Orlov and says he will contact Adam once he has found more information.

Investigate the Scientist's Apartment
Shortly after Adam gets back from Golem City, Sarif will contact him, saying he has tracked down Orlov to Prague and, odder still, has been visiting the city for the past 6 months, the same amount of time Adam has been living and working there. Not believing this is a coincidence, Sarif gives Adam the scientist's address, an apartment near Task Force 29's office. Make your way into the alley between Praha Dovoz and Rose's Garden and you will see it, half hidden behind the tree in the courtyard. Climb on top of the storage units whichever way you see fit and walk along the jutting part of the blue building to reach the apartment. Inside you will find a dead body that Adam recognizes as a Dr. Kasper McFadden who was at the Alaska facility, but must actually be Orlov. Look around the room some more, then use the code 3608 on the level 5 safe to find a file on Adam within. Also, on Orlov's body, is a TYM Vault Keycard, which can be used to access their vault at Palisade Property Bank.

Use my Home TV to Contact Sarif
After you get back from G.A.R.M. and head into TF29's office, Sarif will contact Adam saying they need to talk in private and tells you to call him through a secure link back at Adam's apartment. Make your way there and once more use the remote to call Sarif. Sarif reveals he looked into the 451 facility, where Adam was being kept, and that it has no records of Adam ever being there and, even if nobody knew who he was, it should have been easy to run the serial numbers on his augments to find out. He also says he looked into Kasper McFadden and found out the person did not exist until the day Jensen regained consciousness, a month before he escaped. The only other information that Sarif could dig up was that Orlov had been with Tai Yong Medical for awhile then popped up a few times in 2028 in the Baltic region. Unfortunately, Sarif has no clear answers as the more he digs around, the more questions he has, and the one who could answer them, Orlov, is dead. He will simply tell Adam to make of it what he will on the answers they do have and the mission will complete.
