A thick wall surrounds the base protecting it from the outside, with a additional wall along with a built-in checkpoint located at the entrance of the silo leading to the Machine below.
A lift system was built across the mountain side all the way down to the base surrounding the mountain as well as an underground tram system to allow easy travel between the S.C.A.F colony.
Every high-ranking superior officer carried a key to access the entire facility, that Isaac later acquires to himself.
Another elevator and a ventilation system was also built inside the mountain, leading all the way to the large chamber containing the Machine.
As Scenario Five was commenced, the facility was abandoned and the outside lift was destroyed, trapping anyone up on the mountain.
Locations EditThe Research Compound housed a variety of different sections dedicated for different tasks.
The most important section of the base was the Rosetta research facility, but the complex also had other important sections, such as a warehouse dedicated to storing Markers. Other sections of the base was also put into use of studying the dead, alien-based Necromorphs and also the other, recent variants.
- Biology Sector
- Paleontology Sector
- Geology Sector
Lift system drop-off point Edit
A drop off point for the lift is at the base of the Research Compound. A hut of presumably the maintenance crew is located there.
Base Exterior Edit
A labyrinth of corridors is carved into the icy terrain of the mountain riddled with Markers. The entrance to the Paleontology Sector is located next to the compound gate.Some sort of an overpass is located between the exterior entrance and the Biology Sector entrance.
- According to a S.C.A.F. artifact, the initial fly-overs on the surface of the planet discovered the unusual mountain formation located in the center of a "jagged crater" which would be discovered to have contained the Alien Machine. The personnel responsible for this finding reported sightings of snow-covered, nearly identical obelisks shaped as if two tendrils had intertwined. During these fly-overs, at least one member of these expeditions began experiencing the first stages of the Marker signal induced dementia.
