Station Omega
Move closer to the scraping noise, using the shadows and flickering lights as cover, until you can glimpse whatever is making the sound.Pick up a loose piece of piping from the floor and throw it further down the corridor to divert the entity even farther from your position.Locate a spot with a clear line of sight down the corridor, arm yourself with a nearby piece of debris, and wait for the entity to approach.Spot an open maintenance vent nearby, climb inside, and crawl parallel to the corridor to get ahead of the sound without being seen.
