About Fiat Less
In the early 20th century, in Moria Bay, a catastrophe known as “Dissolution” erupted overnight.
As an Executor created by the Matron, you are about to descend into the ruins consumed by prismatic auroras, carrying out her command: observe, analyze, and reclaim the overflowing Holy Grail.
Game Features
A Fusion of Grid-Based Tactics and Card Gameplay
No longer just a clash of numbers. On a grid battlefield, your positioning and distance directly determine your survival and output.
A Unique Deck-Building System
Choose your class, then embrace the blessings of the Elder Gods. With over 180 cards available, build around collision, spells, or summoning, and strengthen your synergies to amplify your destructive power.
Explosive Power Fantasy
Chase the thrill of a fully realized build. Whether you flood the battlefield with undead ghouls or overwhelm enemies through stacked health, as long as your build forms a complete loop, you’ll experience crushing dominance.
Pure Run-Based Experience
No tedious meta-progression. Every run is a fresh evolution. Within limited nodes, you must adapt your build in real time based on the cards and relics you obtain.
Refined Grotesque Aesthetic
A retro early-20th-century atmosphere combined with a slightly cute yet unsettling hand-drawn art style, delivering a truly distinctive visual experience.
