There is also evidence of him being controlled by someone going by the alias Overseer. He is Isaac Clarke's primary human antagonist throughout the game, and he utilizes numerous automated subsystems as well as teams of Security Officers to halt Isaac's progress throughout the Sprawl.

Graffiti-covered posters of him can also be seen, indicating that he was not well loved among the station's population, the Unitologist portion of it, anyway. Repeating videos of him can be seen in certain areas of the station, urging its residents to evacuate and declaring martial law. A letter from him found later in the game lists his position as Director of Operations aboard the station. Despite being put on like any normal helmet, the suit's helmet still forms an airtight seal, it could be speculated that it uses the same membrane system when the helmet is put on as the more advanced CEC Engineering Suit.Hans Tiedemann was the highest civil authority present on Titan Station at the time of the Necromorph outbreak.The suit also made an appearance in the Previously on Dead Space feature for Dead Space 2, even appearing in the representation of Dead Space's ending.This suit only has 10 storage spaces, holding fewer supplies than any other suit.By contrast, the suit in the remake is much more high quality with less wear and tear, along with being more standardized among other the CEC Engineers aboard the Ishimura.This pre-existing wear slowly disappears more and more as the suit is upgraded. From the beginning of the original game, the suit appears to be badly worn and damaged.Isaac's ID tag can be seen on the left of his chest while wearing the suit, but disappears when the RIG is upgraded.It closely resembles the Standard Astronaut RIG due to the fact that it is almost skin-tight and has a small projection system for holographic display. The Standard Engineer RIG is the most basic form of Resource Integration Gear available for engineers throughout the course of their employment.
