The sector was mainly for research of the extinct Alien race as well as the Rosetta alien-member with a complete laboratory dedicated for it, but later the complex was utilized in understanding the Necromorphs also.
Biological Laboratory Edit
Central Hall Edit
This area connected the different sub-sections of the main building. An elevator access to the upper Rosetta Lab could be found there.
Storage Hall Edit
The storage hall was a warehouse where the Science Division kept all of the found Red Markers.
Rosetta Lab Edit
The Rosetta Lab was located on the second floor of the main building on top of the sphere at Central Hall. The lab was attached to another hall with a decontamination chamber.
The lab housed a control panel that controlled the lab's machinery, an assembly station used to specifically put together the remains of Rosetta as well as another workstation and a control panel of the Assembly station, used to harness the information within Rosetta and making an artificial Codex.
Neurology Section Edit
Neurology Hall Edit
A large door leading to the west of the main central hallway next to the Rosetta Lab led to the neurology section of the building. There was a hallway with a sterilization control room located at the end of it along with a pump room of the corrosive liquid that was used in the sterilization process.
Sterilization Access Edit
Just next to the sterilization control room, there was a small corridor leading to an elevator that went to the pump room of the sterilization system. The pump was located in a tall chamber.
Neurological Laboratory Edit
A large room with a view to the mountain top through the roof-top, the laboratory was mainly used for brain scans and other neurological experiments on the aliens as well as some captured Necromorphs. A dead Leaper could be found on the wall with some drawings of it found next to it. The room also had x-rays of the Necromorph on the machine. A piece of Rosetta was located here.
The room also had a ventilation system and a second floor above overlooking the laboratory below. However, this area was inaccessible.
Crossover entrance Edit
The entrance to the Paleontology and Biological Sector crossover hallway could be found on the second floor of the Neurology Hall after going up an elevator.
