The hellspawn spilled out of the UAC's hidden plateau base in a deluge of blood and fire, but that was only the beginning. It's clear now that the perpetuating evil took advantage of the Director's malleable intent; otherwise the assumption is that the UAC actually had the hubris to meddle with those otherworldly forces when the inevitable outcome has been laid bare time and again. As you step into the cargo lift and descend into the depths of the caverns beneath the plateau, you wonder what was worth burying under all this rock and stone. If the malice you faced to get here was just scratching the surface, what lies in wait in the darkness below? You steel yourself for what is to come, for anything given this much effort to conceal can result in nothing less than A Stygian Anguish.
