UNDERDEEP

UNDERDEEP is an idle RPG that lets you dive deep into dungeon exploration and mapping, set in a gritty, immersive fantasy world. Blending the charm of classic RPGs with modern idle mechanics, it offers a rich and thoughtful gameplay experience.

Character Creation

Your journey begins by creating your own character. Name them, select a visual style, and enter a world of adventure with the one who represents you.

Job System

You’ll begin as a Newbie, a complete beginner. But as you gain experience, you can evolve into a wide range of roles—warrior, rogue, ruler, or crafter. Experience a highly flexible job system where your growth determines the path you take.

Mapping

At the heart of dungeon exploration lies mapping. Locations are automatically recorded as you explore, and you can place your own custom markers to keep track of important spots. Your observation and note-taking skills are the key to successful expeditions.

Over 500 Unique Items

Weapons, armor, accessories, and more await deep within the dungeon. Use your gear strategically to challenge increasingly dangerous and rewarding areas.

Skill Customization

Build your own strategy with unique skill combinations. Some skills can synergize dramatically, amplifying your power. Craft your ultimate build and conquer the depths your way.

Idle-Friendly Exploration

Whether you prefer hands-on control or automation, you can choose between manual or auto actions during exploration. Set your strategy beforehand, and your character will continue adventuring even while you're away. Perfect for busy players who want to keep progressing.

Light Asynchronous Multiplayer

You might encounter characters created by other players inside the dungeon. Customize your “dialogue” and “behavior” settings to prepare for these spontaneous meetings. Enjoy a relaxed, asynchronous multiplayer experience that lets you connect without pressure.

Karma System

Your behavior in the dungeon affects your character’s karma. Will you walk the path of light—or descend into darkness? The choice is yours.

In the shadowy forest near the royal capital, a mysterious dungeon teeming with monsters suddenly emerged. The first to enter was an unnamed man, who returned bloodied, clutching a chest of gold. Word spread like wildfire, igniting the hearts of all who craved wealth and fame. Mercenaries with swords, knights chasing glory, and fearless adventurers flocked to the forest. They say a legendary treasure, powerful enough to shake the throne itself, lies hidden deep within. And now, you stand at the entrance. Will you seize your destiny—or be consumed by the darkness? Your story begins here.
