About this game
About us
We are a tiny team of detective game enthusiasts. Inspired by Return of the Obra Dinn and The Case of the Golden Idol, we created Abyss Archives as a small tribute to the developers behind both games.
About the Game
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?
A suspenseful story where a mining accident from ten years ago intertwines with a supernatural incident in the present.
Use old photographs to trace fragments of the victims’ memories from when they were alive.
Search for clues in character conversations, personal belongings, and environmental details.
Collect Keywords and use logical reasoning to place them correctly and reconstruct the case.
Freely investigate death scenes instead of simply following the story and choosing preset answers.
Lead the deduction yourself. Use any means necessary in pursuit of the truth.

做推理游戏的难题：线索到底要怎么藏？！
这张图里，有一个能够判断人物身份的线索，但如果我们直接把它框出来——它还算推理吗？大家好，我是《深渊档案》的制作人阿甘。在做这款推理游戏的时候，我们一直很纠结一个问题：线索到底应该做到什么程度呢？做得太明显，玩家一眼就看出来了，那基本也没什么推理的过程。但藏得太深也不行，万一玩家刚好和我们对不上脑电波，找半天都不知道自己漏了什么，最后只能去翻攻略，那体验肯定也不好。所以在《深渊档案》里，我们更希望线索本身就是现场的一部分，它可能是某个人说过的一句话，可能是角色身上的一件东西，也可能只是一个第一次看到时，你根本不会特别在意的细节。但随着你找到更多信息，再回头把它们放在一起看的时候，突然就能对上：“原来这里早就告诉过我了。”我觉得这也是推理游戏特别有意思的地方。不是看到一个东西，游戏告诉你“这是关键线索”；而是你先有了一个猜测，再从现场里找到东西去证明自己的判断，有点像做数学题的时候，答案算出来了，再换一种方法验一遍——发现真的对了，那一下还是挺爽的。当然，我们也不会把所有东西都藏起来。一些基础资料和必要的信息还是会直接给玩家，让大家先搞清楚这里有哪些人？大概发生了什么？再从这些明面上的信息出发，一点点往下挖，最后把藏在下面的真相推出来。所以如果是你的话：你更喜欢线索给得明确一点，还是更喜欢自己从现场里慢慢发现？欢迎加入我们的玩家群和我们交流！另外，如果你对《深渊档案》感兴趣，也欢迎把游戏加入Steam 愿望单，感谢大家支持，我们下一期开发日志再见。《深渊档案》交流群：992397632Read full article on Community Announcements (OKJOY)AnnouncementsOfficial
一张老照片，如何把玩家送回十年前的命案现场？？
这是一张很普通的老照片。但只要站在正确的位置，它就能带你回到十年前——回到照片中的人已经死亡之后，现场还保持原样的那一刻。大家好，我是推理游戏《深渊档案》制作人阿甘。今天想聊聊游戏最核心的玩法之一：我们为什么要让玩家通过一张照片，亲自走进过去的死亡现场？因为我们希望通过这一张照片，链接十年前和十年后的。解开十年前“会吃人的煤矿”和十年后矿坑酒店的灵异事件真相，这就是《深渊档案》里的老照片机制。一张照片不会直接告诉你答案，它只负责把你送到真相曾经发生过的地方。剩下的，就要靠你自己去看了。玩家能做的，是在现场自由移动，观察人物、检查他们携带的物品，并听取案发时留下的对话。比如，你可能会在一个人的手机里看到一条短信。短信没有直接告诉你发件人是谁，但结合现场其他信息，就能推断出两个人之间的关系。你也可能会在角落里发现一个工厂颁发的杯子。上面的年份和名字看起来只是普通文字，却可能帮助你确认某个人的身份。这些信息都可以被提取成关键词，成为之后还原事件真相的依据。我们选择这种方式，是因为比起通过一段回忆动画告诉玩家“当年发生了什么”，我们更希望玩家亲自走进现场，通过自己的推理一步步探索出事件的真相！如果你对我们游戏的玩法感兴趣的话，欢迎前往Steam添加到你的愿望单中，非常感谢！我们下一期开发日志再见。《深渊档案》交流群：992397632Read full article on Community Announcements (OKJOY)AnnouncementsOfficial
做推理游戏的第一步：不告诉玩家任何线索！
如果只给你一个静止的案发现场，再给你几个看起来没头没尾的谜题，你觉得自己能不能把真相推出来？大家好，我是《深渊档案》的制作人阿甘，第一期开发日志，先简单聊聊这是一款什么样的游戏。《深渊档案》的灵感来源，我们也不避讳，主要来自《奥伯拉丁的回归》和《金偶像谜案》。我很喜欢它们的一点是：推理不是依靠剧情推进的，而是把线索放在现场里，让玩家自己去观察、联想和推理，《深渊档案》想做的，也是这种体验。在游戏里，你一开始不会知道现场这些人叫什么，也不知道他们的职业、身份和关系。你能看到的，只有一个现场，以及一些可以调查和互动的内容。你需要从这些内容里拆出关键词，再结合人物位置、对话、物品和现场细节，把姓名、身份、关系和事件经过慢慢拼起来。而真正关键的答案，很多时候并不在最显眼的地方。它可能藏在某个人随口说的一句话里，也可能藏在一个不起眼的物品上。等你后面再回头看，才会发现答案其实早就摆在那里了。所以，《深渊档案》不是游戏带着你推理，而是希望你真的像侦探一样，靠自己的判断接近真相。回到刚开始的那个问题：如果只给你一个静止的案发现场，和几个谜题，你觉得自己能不能把真相推出来？如果你对《深渊档案》感兴趣的话，欢迎把游戏加入你的愿望单。感谢大家支持，我们下一期开发日志再见。《深渊档案》交流群：992397632Read full article on Community Announcements (OKJOY)AnnouncementsOfficial
