About Echo Abyss

Echo Abyss is a browser-based text adventure with an AI Dungeon Master. You type; it writes the consequences. The rules, stats, monsters and endings are handled by the game server, not improvised by the model.

What it is

A ten-floor dungeon, a brother who disappeared, a bounty of ten thousand gold and a barony. You start at the entrance with an old sword, a healing potion and no answers. The AI Dungeon Master narrates; the server resolves the rules.

What the AI does — and does not do

The model writes scenes, dialogue and consequences. It does not decide your HP, gold, inventory, depth, boss state or ending. Those are calculated by the game. This keeps the story flexible without letting the model hand-wave a win.

Free to start

The official API is free but slow. You can use your own DeepSeek key for faster turns. No account, download or payment is required to enter.

Saves and privacy

Progress is stored in a server-side SQLite save keyed by a browser cookie. There is no account, so clearing cookies, changing domains or switching browsers creates a new save. The game stores the story, stats and API configuration; it does not ask for your real name.

Content

Ten floors, 15 random events, 13 endings, 28 achievements and a hidden brother storyline. The game is designed for short sessions but can be played for an hour or more in one run.
