Gotcha Gotcha Games has announced Cthulhu Mythos ADV for PC (Steam), iOS, and Android. The game is scheduled to release in September of 2022 but only supports Japanese.

Cthulhu Mythos ADV is a 2D adventure game inspired by Lovecraft’s Cthulhu Mythos. The protagonist of the game wakes up in an abandoned hospital, and together with their companions, must face off against strange monsters and make their escape.


Players will explore the abandoned hospital gathering items and information, with some actions in the game being determined by rolling dice. The game displays an action’s chance of success as well, with things unfolding differently based on the results. The rate of success for dice rolls is determined by the protagonist and their companions’ stats, and the protagonist’s stats are set randomly at the start of the game.

The results of the dice rolls may also eat away at your sanity and cause you to take abnormal actions. Screenshots for the game show a “SAN (sanity)” meter in the upper left corner of the screen and managing this meter will likely be an important aspect of the game. Furthermore, the game has 7 different endings, and players will be able to access hidden information and uncover the truth by maintaining their sanity above a certain level.

The official Twitter account for the game introduces several creators involved with the project, including:

Scenario writer: Kuze Kuze
Character and key visuals: TAKOLEGS
Background illustrations: Metoko
Mythical creature illustrations: Murasaki Jazi
Memory fragment illustrations: Monokubo
Title logo: Ake

Kuze Kuze is a VTuber who streams Call of Cthulhu TRPG scenario creations and play sessions, TAKOLEGS is the illustrator behind Fate/Grand Order spirit illustrations like Xu Fu, and Metoko is an illustrator who is also making their own game based on Cthulhu. Cthulhu Mythos ADV seems to be bringing together a number of creators who are involved in Cthulhu-related works.

Gotcha Gotcha Games is a subsidiary of Kadokawa and known for making and supporting the RPG Maker series. The company says that Cthulhu Mythos ADV is their first original game.

Cthulhu Mythos ADV can be found on Steam here.
