The Nintendo Switch version of "Aooni: The Horror of Blueberry Onsen," the latest title in the "Aooni" horror game series where puzzle-solving and terror intersect, is set for advance release on Friday, April 25, 2025!
This time's setting is a hot spring inn that was once popular as a "hot spring for becoming beautiful" but has since become a ruin.
Familiar characters from the series will once again find themselves caught up in strange phenomena at the former famous hot spring!
Evolving Features Like Co-op and High-Speed Mode! A New Aooni Horror Experience
In "Aooni: The Horror of Blueberry Onsen," set in a ruined hot spring hotel, Hiroshi, Mika, Takuro, and Takeshi visit the location for the purpose of filming for the YouTube channel "Mika Channel."
There, they encounter an unknown "**suspicious man**" and a mysterious entity called "**Ai**." Players will unravel the secrets of the hot spring while escaping from the attacking grotesque entities alongside the characters.


Furthermore, the character illustrations have been completely revamped.
While featuring new visuals, you can also play with the old version's design by setting the protagonist's name to "Maenokao" (previous face).

Also, the fast-forward mode, which was well-received in the previous game, has evolved in this title, allowing you to play at up to 16x speed.
For players who have already cleared Normal mode or streamers, this will likely offer an enjoyable new challenge!
