深渊档案 Abyss Archives

In a small northern city, construction has begun on a new landmark building. As the first foundation pile is driven into the ground, pitch-black wastewater suddenly gushes out, followed by strange noises from deep below. The workers flee in terror, and construction is brought to a halt.

The land was once home to an abandoned mine. Ten years ago, a mining accident that shocked the entire city claimed the lives of every worker who descended underground. Now, it seems those restless spirits have awakened once more beneath the earth.

Sent to investigate, you must uncover the truth behind the mining accident.

Your investigation begins with a series of old photographs. Locate the places where they were taken, and each one will pull you back to key moments surrounding the mining accident.

These memories are incomplete. They leave behind only fragments, conversations, and scattered details. Clues often lie in the smallest, most easily overlooked places, so you must observe carefully and connect the pieces yourself.

During your investigation, you will collect sets of Keywords, which may refer to people, locations, or even hidden motives. Place them in the right spots to fill in the missing information, gradually reconstructing the events of the case, the relationships between its characters, and the truth behind it all.

Unlike traditional detective games driven by dialogue and story progression, Abyss Archives puts you in front of death scenes, fragmented memories, and limited clues. You are the one who must observe, connect the clues, and draw your own conclusions. Will you be able to uncover the truth?
