Our take on Gibbous - A Cthulhu Adventure

Rather than treating cosmic horror as purely grim, the game pairs occult conspiracies and abominations with recurring comedy, a transformed talking cat, and a multi-character adventure spanning several regions.

What is Gibbous - A Cthulhu Adventure?

Gibbous is a comedy cosmic horror adventure set in Darkham, where cults are appearing and the Necronomicon has resurfaced.

The story follows detective Don R. Ketype, librarian Buzz Kerwan, and Kitteh, a cat transformed into a talking abomination. The three protagonists travel from Lovecraft-inspired locations to Transylvania, investigate ancient conspiracies, and encounter cosmic and human-made threats. The game combines hand-painted environments, traditional 2D animation, voiced characters, animated cartoon scenes, and a soundtrack recorded with live instruments. Its lengthy cinematic narrative spans continents, pairing frequent humor with a darker overarching plot. An integrated hint system provides assistance during progression, and characters have voiced responses for many possible combinations.
