Zero Sum 1.0 (EP.1) (English, Spanish, Russian)

Zero Sum delivers one of those corporate thriller experiences that feels uncomfortably relevant to our data-driven world. You’re stepping into the shoes of a testing manager who lands an unexpected promotion to lead Project Icarus, tasked with perfecting an algorithm designed to exploit taxi users at their most vulnerable moments. The premise alone had me hooked — there’s something deeply unsettling about building a system that profits from people’s desperation.

The visual novel format works perfectly for this kind of psychological thriller. Every choice you make shapes both the algorithm’s development and your character’s moral descent. What starts as corporate advancement quickly spirals into something much darker when you realize your promotion wasn’t random luck.

When Data Becomes Your Weapon

The Phoenix algorithm concept is genuinely chilling in how realistic it feels. You’re essentially weaponizing user data to maximize profit during emotional vulnerability, and the game doesn’t shy away from the ethical implications. The tension builds nicely as mysterious figures start watching your every move, suggesting you’re not the only player in this dangerous game.

The enhanced version gives you access to all story branches and adult content without restrictions. The UI can feel a bit cluttered during data analysis scenes, but the narrative tension more than makes up for it. This thriller knows exactly how to make corporate espionage feel personal and terrifying.
