Publisher Hakony has released "UNDERDEEP," an idle RPG where players can enjoy dungeon exploration and mapping, for PC (Steam).

An idle RPG featuring dungeon exploration and mapping

*UNDERDEEP* is an idle RPG—said to be influenced by *Wizardry* and *Artes Note*—that features engaging dungeon exploration and mapping.

The game automatically records the locations you visit, and you can place your own markers on the map. You start as the “Newbie” class, and as you gain experience, you can evolve into various other classes, such as combat classes, crafting classes, rulers, and underworld figures.

The game is packed with classic RPG elements, such as building character builds through skill combinations and collecting over 500 types of items, including weapons and armor.

You can also set a strategy in advance and have your characters explore automatically, allowing you to let the game run in the background while you’re busy with other tasks on your PC to automatically collect items and more.

Inside dungeons, you can engage in light asynchronous multiplayer by encountering characters created by other players. Furthermore, there are branching elements where your character’s “Karma” changes based on whether you act good or evil, making for a surprisingly deep gameplay experience.


"UNDERDEEP" is currently available for PC (Steam). It is priced at 1,480 yen, but until November 13, you can purchase it for 962 yen—a 35% discount.
