Millenials might remember the 2008 freeware horror game Ao Oni about a strange blue demon that chased you, as the player, around a haunted mansion. It was a very simple 2D game, but its atmosphere did the trick.

A remaster of the original game was released in 2024 and we now have a new game coming our way! Unlike the original game, where the setting was a haunted mansion, this one is going to be set in an onsen!

Namely, based on the information we have from the developers, Ao Oni: The Horror of Blueberry Onsen is coming out for the Nintendo Switch on April 25, 2025, with a PC (Steam) port listed as “coming soon.”

The developers have released a short teaser video with some in-game clips you can check out:

The new game will have the feel of the original one, but it will also have some new features like co-op play, chat, character conversations, 16x speed mode, and online rankings. There will also be new species of blue demons that the players will have to run away from.

The official synopsis reveals the following:

The once-popular hot spring inn known for its “beauty-enhancing hot spring” is now a ruin. There was a rumor that it was haunted. Hiroshi, Takeshi, Mika, and Takuro visit the abandoned hot spring inn to record “Mika Channel” and encounter a “suspicious man” and “Ai” there… What is the Blueberry Hot Spring found in the abandoned inn, and what awaits them in its deepest depths…? Can Hiroshi and the others escape safely?

When released, the game will be playable in English, Japanese, Korean, Traditional Chinese, Simplified Chinese, French, Italian, German, Spanish, and Indonesian languages.
