About this game

Double-sided Aces is a text-based adventure game blending suspenseful puzzles with multi-route romance.

You will play as Yang Zaize, an undercover police officer investigating the cutting-edge chip company [Kuin Science], only to find yourself entangled in a complex conspiracy between law and crime. Through interactions with six characters of diverse personalities and intricate backgrounds, your dialogue and action choices will shape branching storylines, leading to multiple endings.

Every decision determines Yang Zaize’s fate. Will he uphold justice or succumb to darkness? The answer lies in your hands.

Two Cities, Two Syndicates

[Kuin Science] is renowned for its chip design and biotechnology, pioneering implantable chip innovations. However, authorities suspect deep-rooted collusion between this corporation and the [Du Group] — a violent organization entrenched in real estate, gambling, and mining. The syndicate’s leader remains shrouded in mystery, and the identity of their heir is concealed behind layers of deception.

 

Dual Identities

A spectral detective who appears frequently, a enigmatic doctor met at a bar, a genius hacker who is also your stepbrother, a spirit medium bridging the living and the dead, an ambiguous superior, and a childhood friend with hidden ties…

Each character wears two masks — are you touching the truth, or meticulously woven lies?

 

Dual Worlds

As the story unfolds, the appearance of a "ghost" unveils secrets spanning the realms of the living and the dead, intertwining Yang Zaize’s destiny with past-life entanglements. The boundary between reality and reincarnation blurs, forcing Yang Zaize to navigate technological conspiracies, gang warfare, and karmic cycles in a deadly game that transcends life and death.

In Double-sided Aces, players take on the role of a character, navigating choices and interactions to win the hearts of six distinct and captivating characters, embarking on a thrilling adventure.
