Warning: Access denied. Continued efforts will be denied... forcefully. Concede, Robin Goodall.
― Al-An, presumably

This unnamed Alien Base is set to appear in Below Zero. What purpose it serves and why it was constructed is currently unknown.
The exterior is built similarly to that of the Primary Containment Facility in the Crater, as seen in the concept art.
Developer notes suggest that this base is merely the lower half of a much larger facility, with an elevator inside the base leading to an open balcony. An Alien Arch is located on this balcony, as well as a terminal that supposedly leads to the end of the game.[1]
Story
During her search for Jo Jeffreys, Robin Goodall will stop by the Alien Base, only to be denied access by an unknown voice, who threatens her. Taken aback by the facility knowing her name, Robin reports to her sister, Sam Goodall, who warns her that an electrical storm is coming, but lightning confirms that it's already arrived. On her way out of the cave, the electrical storm renders the cave unstable, and an avalanche blocks the cave entrance and destroys the Research Base.[2]
