Beneath the lowest levels of Area 51 lies an abandoned sector known only as "Sub-Facility Echo." Originally sealed decades ago, it now harbors a terrifying secret - an invasive species resembling a symbiont that escaped containment and began to multiply. Hidden from satellite scans, the underground chambers are overrun with pulsating cocoons, each cradling embryonic horrors suspended in a gel-like substance. At the heart of it all is a massive, unknown organism-part flesh, part tendril, its limbs slithering through the darkness, nurturing the eggs with a sickly bioluminescent fluid. The walls breathe. The air tastes wrong. Whatever lives there isn't just growing- it's evolving.
