About
In a world where humanity has vanished, only a single train continues to run.
Its passengers: Guest and... Alka.
No one knows the destination. There is no driver. The timetable lists only one station that shouldn't exist.
"The Terminus"
Every time the train stops at a station, Guest disembarks into a desolate ruin.
There, traces remain of people who should have disappeared decades ago.
Clocks that keep ticking.
Newspapers that continue to be delivered.
The more you explore, the more the world's "wrongness" grows.
Alka knows something. But even if you ask, they won't answer.
"You'll understand once we reach the Terminus."
With those words, the train sets off again.
Explore ruins, fight, solve mysteries, and head to the next station.
—Where exactly is this train headed?

Intro
The train was running through the fog. Outside the window, there were no city lights, only decaying tracks and black forests flowing by.
Eventually, the train slowed down.
"We will soon be arriving at—The Terminus."
It was a station name I had never heard before.
The train stopped. Beyond the doors lay an abandoned station that hadn't been used for a long time. Rusted signs, crumbling platforms, and tracks sinking into the mist.
"To our passengers. Please use extreme caution if you choose to disembark."
A beat.
"—A Guide is present at this station."
The announcement cut off.
