"Train incoming. Mind the gap."
The voice echoed cleanly through the station.
Artificial.
Too calm for the world it existed in.
A man in uniform stood near the edge of the platform with his hands behind his back as the train slowly rolled in. Its headlights cut through the dim tunnel first before the rest of it emerged from the dark.
People nearby barely looked at it.
Commuters.
Civilians.
A woman sipping coffee from a paper cup. Two men arguing quietly over something on a tablet. Somebody laughing into an earpiece.
Normal.
Or at least whatever passed for normal underground.
The uniformed man watched the train carefully as it slowed.
Something felt wrong immediately.
Then he saw it.
A smear of blood across one of the windows.
His eyes narrowed.
The train hissed loudly as it came to a stop.
The doors slid open.
And his stomach dropped.
People screamed almost instantly.
One woman turned away and vomited hard onto the platform floor.
