Happy Monster

Happy Monster is an action game set on a newborn Earth, a century after human civilization has vanished. You play as Sartos, a warrior of the Stellar Clan of dragonkin, who crash-landed on Earth after the Demon God attacked the dragonkin homeworld of Shamuron. As Sartos protects his new home and fights corrupting forces, he uncovers the mystery of the hidden Dragon Crystal and the truth about his bloodline. He must help restart dragonkin civilization.

The dragonkin’s fall

After their king falls, the Demon God leads an attack on Shamuron, seeking to devour the universe. Without the protection of Draconic Soul power, the planet falls and its dragon tribes are scattered into exile. The Stellar Clan, carrying the ember of hope, lands on Earth, where the Demon God’s forces still lurk. The story of the dragonkin’s rise and fall, and Sartos’s personal fate, unfolds through hand-drawn comic chapters.

Evolving combat

You fight through corrupted otherworlds overrun by monsters, combining skills and draconic forms with attributes absorbed by devouring enemies. Skill Chains, Dragon Fury Bursts, Devour & Evolution, and Relic Abilities support different ways to fight and clear hordes. You grow stronger as you battle and unlock multiple draconic forms, each with its own talent trees and ability branches.

In story stages, you learn to use different forms and unlock combat techniques to meet changing stage mechanics and environmental challenges. Stage rewards and a pre-battle shop offer skills, runes and items; forging functions include reforging, synthesis and alchemy, letting you build for different combat approaches.

Story and challenge modes

Challenge mode lets you choose your starting form and skill combinations, then face bosses across randomized terrains and compete for record clear times. The bosses draw on Cthulhu-esque styles, while environments include plains, swamps and magma caves. Each setting calls for different strategies.
