You believed only that rumor and stepped into the closed underground space.

Aiming at you
There is something chasing you.
Moving in the dark, never giving up.
Hold your breath and move carefully.


Sometimes, you have to stand up
You have the means to resist.
Sometimes running away isn't enough.
The chances are slim, but the possibility is there.
