The Arktos Pharma biome lab is a section of Arktos Pharma, located underground in the Forest region of Appalachia.


The lab consists of several underground habitats, designed and utilized for projects by the Arktos Pharma Company before the Great War.


This underground location can be reached by entering the right-hand elevator behind the reception desk at Arktos Pharma. The underground habitats are organized around a central, multi-tiered hub that houses the central feeder pump and the governing intelligence that carries the project out.

There are three Habitats: A (forest), B (tundra), and C (swamp). Each contains a feeder pump and offers an open space with several turrets, natural obstacles, and robot caretakers. The security door located in the lower level utility area leads to the generator and laboratory room, and requires the player character to collect three code fragments (Biome lab: Code fragment A, B, and C) or type the following number: 970930.
