[All Characters & Weapons Free to Unlock — Craft your own lineup]
Freely farm character fragments and forging materials to unlock your favorite characters and weapons at your own pace. No forced progression, no rigid templates—just the joy of free cultivation and strategic experimentation. Focus on strengthening your core squad or exploring endless tactical possibilities.
[Destinies intertwine — Meet demons of a hundred faces in the DNA]
You will step into a land where magic and machinery coexist, playing as two protagonists with vastly different backgrounds. Encounter a variety of demonic beings with their own perspectives as you engage in constant battles and exploration to uncover the truth behind a thorny fate, ultimately bringing an end to the spiral of suffering.
[Swap between melee & ranged weapons — Freely create multi‑dimensional weapon combos]
In battles, you can freely switch between melee and ranged weapons, allowing characters to break free from the limitations of a single weapon class. Choose from a variety of cool melee weapons such as whipblades, crossbows, and even heavy firepower like sniper rifles, grenade launchers, and high-tech hover guns to create your unique weapon loadouts.
[Exhilarating hack‑and‑slash battles — Master agile moves and mow down hordes]
Engage in fast-paced combat against waves of relentless enemies with the freedom to utilize both close and long-range attacks, as well as aerial assaults and ground takedowns. Bask in unexpected and thrilling battle experiences through diverse combat gameplay including tracking, reconnaissance, and rescue missions.
[Customize your look with dyes — Mix & match—colour weapons & outfits freely]
Dye and switch at will—take full control of your weapon and character aesthetics. Swap color schemes on the fly to match your combat style with your personal flair. Combine a wealth of accessories—from elegant headpieces to lively waist ornaments—whether for refined beauty or playful fun, the choice is yours.
================================
In the long and repetitive dream,
Quicksand constantly pours down.
The compass of destiny starts to tick.
The two wake up and embark on their separate journeys.
On this shore, you emerged from a perilous situation but were exiled to the harsh North Border, struggling to survive.
On the other shore, you found yourself in a maelstrom of power, striving to escape from a cage woven with conspiracies.
No need to bid farewell.
As time perpetually flows forward,
As the two shores will eventually meet,
You will meet each other one day.
