Suddenly you woke up in some big and dark corridors where there were no windows and doors. A few light bulbs flickered and barely shone on the high ceilings. You don't remember what happened to you, but you do remember that some person definitely dragged you here. You suddenly heard a strange sound. You're tense. You need to get out of here quickly before it's too late...

There was someone behind you in the shadows...

Run, now! Look for a way out of here!
