Blue Protocol: Star Resonance expands the Blue Protocol universe with a vibrant MMORPG experience. Create your own hero, team up for strategic raids, or simply relax and have fun with friends fishing, crafting, and endless exploration. Adventure awaits!

In the fantasy realm of Regnus, the once-stable cycle of star-essence that sustains all life has fractured, unleashing rampant disasters and environmental decay across the land. The supreme deity race abandoned their polluted world, leaving mortals to shoulder the burden of survival and restoration. Players awaken as rare Resonators, gifted with the unique ability to attune to, and answer the call to gather scattered star-essence fragments, forge alliances, and uncover the ancient secrets necessary to repair the cosmic cycle.

Their journey carries them through lush forests, scorching deserts, crystalline ruins, and even toward the legendary Sky City, as they tackle dungeons such as Rocksong Temple and Shattered Sand Sea to activate star-sigil mechanisms and reclaim lost fragments. Along the way, they clash with a shadowy Dark Cult intent on resurrecting a fallen god to reshape Regnus under a new, oppressive order. The saga culminates at the Void Gate, where all Resonators must unite their powers to confront the Abyssal King, reignite the central star-essence core, and restore cosmic harmony.
