Steam is listing that Mediascape will release Team Shanghai Alice’s Touhou Kikeijū: Wily Beast and Weakest Creature, the 17th main game in the Touhou Project game series, on September 10.
Touhou: Hidden Star in Four Seasons, the 16th and latest main installment in the Touhou Project series, debuted at the Comiket 92 event in August 2017.
ZUN’s Touhou Project Dai-16.5-Dan Hifū Nightmare Diary ~Violet Detector game launched at the Comiket 94 event last August.
ZUN said the game is darker than usual, and is a bit more of an “offensive shooting game” with lots of animal elements.
