About Fataclysm

Fataclysm is an adult text-based game with turn-based combat by Jupitarian, built in HTML and uses 2D CG with AI art. You lead a group of heroes trapped in the Excessive Expanse, a realm formed when a multiversal disaster collides fragments of space and time. Their goal is to escape, no matter how many attempts, while confronting fantasy, sci-fi, and transformation themes.

The game remains in development, with the paid v0.2.0 build released July 11, 2025, for Windows, Linux, and Mac, in English, and uncensored. The latest update adds a new fifth companion, including fresh weight-stage art, skills, and descriptions. It also introduces party-building and duo assignment mechanics, many new dialogue lines, event choices after recruiting her, and a bun-created multi-part Penitentiary sequence. Several Leona scenes were rewritten for consistency.

Developer's description

Enter the Excessive Expanse and experience the FATACLYSM - a multiversal calamity that has brought together disparate fragments of space and time to a realm of expansive proportion. Take the reins of a group of unfortunate heroes who have committed themselves to escaping the Expanse, no matter how many tries it takes... even if it costs them their waistlines over, and over, and over again.​

I love this game, wish there was more permanence to choice/transforms, and obviously wished there was more content. Pros: Subject matter is hot. The transforms are hot. The AI renders are pretty good, and the character all look consistent. No…

I'm not really into obesity, but damn!! This is a really good game! The fights are satisfying, slightly random, but rewarding for a tactical approach and not mindlessly clicking random options. Every hit makes the opponent or one of our…

I'm not a huge fat guy, but I'll admit this game is a lot of fun. They did my favorite thing and integrated game design with the kinks/ero aspects of it and it works damn well. Also, if you don't…
