Step into the suffocating void of Research Facility G-1-6, now eerily silent after an unexplained communication blackout. As a lone operative, your mission is to reestablish contact and uncover the truth behind the disruption. Armed with the AEGIS Scanner, you’ll explore the facility’s shadowed halls, revealing hidden details and tracking what the eye cannot see. But danger lurks in the darkness, and something unknown watches from the shadows. Stay sharp, stay silent, and survive long enough to uncover what’s really going on here.
