About This Game

Discover the Rules of the Anomaly. Survive the Night.

A deduction-based survival horror game set aboard a long-distance train.

A seven-day train journey. Then, an incident occurs: an anomaly appears somewhere on board.

Your goal is not to fight it.

Understand what the anomaly does, figure out its rules, and take the right precautions to survive.

Day — Investigate

The daytime is when you are free to act.

Explore the train, talk to passengers, and investigate the conditions under which the anomaly attacks.

A seemingly casual conversation or a subtle change inside the train may reveal a clue to its behavior.

Gather information and deduce:

• The conditions that cause the anomaly to attack

• Who it will target

At first, much of the information is hidden.

By exploring and observing the train, you will gradually uncover the nature of the anomaly.

Night — Survive

When night falls, the anomaly begins to roam the train.

But you cannot freely explore the train at night.

You must use the information you gathered during the day to prepare for the night in advance.

Your decisions determine what happens during the night.

Make the right choice, and the anomaly may pass by your room without noticing you.

Make the wrong choice, and you may lose your life.

Even in Death, Knowledge Remains

You cannot know all of the anomaly's rules from the beginning.

Sometimes, an unexpected behavior may cost you your life.

But the knowledge you gain from each failure is never lost.

"This anomaly appears when that happens."

"I'll be attacked if I stay in this room."

With each failed attempt, you learn more about how the anomaly behaves.

There are no abilities or stats that grow stronger.

Your own knowledge is your greatest tool for survival.

Don't Fight. Understand.

The anomalies aboard this train cannot be defeated.

You don't need a gun or a sword.

You need to gather information.

Then use that information to deduce the correct rules.

Discover the rules of the anomaly. Survive the night.

And make it all the way to the final station alive.
