This is a certain research facility. A monster created in an experiment escaped, the facility was devastated, and it is believed there are no survivors. Now, someone has arrived at this place.
Your role is up to you! You could be a survivor, or even another experimental subject!

This is an abandoned research facility.
The facility stands deep in a mountain range, in a place that seems to stubbornly refuse to appear on any map, as if hiding the schemes of those who dwell beneath the earth.
Once, researchers were here. Men and women in white coats who, under fluorescent lights, wrapped their desires in the guise of science. What they were trying to create is now impossible to know. After all, every single one of those researchers has vanished. 'Vanished' is a gentle way to put it; to be more precise, one should say they were 'devoured.'
The building is half-destroyed. Concrete walls are gouged by beastly claw marks, steel reinforcements are twisted like pulled candy, and pipes and insulation protrude from the ceiling like entrails. The fluorescent lights in the hallway flicker intermittently, their unstable glow reflecting in puddles on the floor like the glint of an eye.
Silence. However, it is not the kind of silence that brings relief. It is the sort of hush that falls when birds go quiet before a storm.
Inside this cradle that birthed a monster, if any sound is made, it will surely reach 'its' ears.
Even now, the massive body that crawled out of its eggshell prowls somewhere in the darkness.
