You will play through the main story line until you leave the space station to go on a Zero Gravity spacewalk to find Dr. Lorenzo Calvino's body and keycard. Upon returning to the
Hardware Labs, you now have access to
Dr. Calvino's Workshop.
Go inside and head down the stairs, locating a large red toolbox and finding
Dr. Calvino's Tumbler on top. Pick up this red tumbler and bring it across the room to the small scale sitting on the table. The item will be automatically placed on this scale and it will reveal and open a secret door with 2 neuromods and a cabin keycard inside. You will also unlock the achievement.
The information for this solution is located in the same room; available on the computer via emails.
