It has been confirmed that in 'Phantom Blade Zero,' the martial arts action game currently under development by S-GAME, the main story will change depending on how players progress through side quests.

This information was revealed in a developer interview video posted on the official Phantom Blade X (formerly Twitter) account on the 16th. In the video, S-GAME CEO Soulframe Liang stated that choices made during side quests can have a meaningful impact on the main storyline.

Liang explained that "Phantom Blade Zero is built on 'Wu' (martial arts) and 'Xia' (inner righteousness)." He noted that while 'Wu' represents external expression through combat, 'Xia' symbolizes the protagonist's inner commitment to others. He added that as the protagonist travels to various regions and encounters different people, players will be able to choose how to interact with them.

"He emphasized, "One thing I can say for sure is that helping others can trigger a butterfly effect. If a player acts honorably, it will certainly influence the protagonist's story of revenge and love in the main plotline accordingly.""

Meanwhile, 'Phantom Blade Zero' is a martial arts action game being developed by S-GAME using Unreal Engine 5. With its release confirmed for September 9, 2026, the game follows a mortally wounded swordsman who, with only 66 days left to live, must uncover a massive conspiracy within the martial arts world while on the run, proving his mastery and reclaiming his identity and the truth amidst a landscape of crumbling order.
