You awaken on the cold floor, your head groggy and your limbs aching. You feel an acute stinging in your arm, and you discover a puncture mark. Have you been drugged?

You stand up uneasily, finding yourself in what appears to be a train depot. A single tram car sits on the tracks, its door open and electronic lights flickering within. The massive depot is made entirely of cement and steel, and pulsating red lights waver on the walls, ceiling, and floor. There are multiple doors around the building, each leading to what appears to be offices, supply rooms, and break areas.

The depot is entirely silent, save for an occasional and muffled thumping from somewhere you can't quite place.
