Zero Sum — an adult visual novel where your conscience has a price
Zero Sum is an adult visual novel with thriller elements. You’re an ordinary manager who gets promoted to lead a secret project called “Icarus.” Your new job is to make people pay more. Your tools are data, algorithms, and other people’s weaknesses.
The problem is — you don’t know who you’re really hunting. And when the truth starts to surface, it’ll be too late to run.
🎭 Story
An ordinary testing department manager unexpectedly gets promoted to lead Project Icarus. His task is to finalize and bring to market the “Phoenix” algorithm — a system that analyzes user behavior and dynamically raises taxi prices during moments of vulnerability.
The more the algorithm learns about customers, the more money it makes. Soon, the protagonist realizes: his promotion isn’t a gift from fate. It’s a ticket to a world where morality and profit never align. Every decision changes not just the project’s fate — but his own.
But the truth doesn’t stay hidden forever. Someone already knows too much about the project. Someone is watching. Someone is waiting for a mistake. And when it happens — there’s no turning back.
⚖️ The choice is yours
- Give in to greed and the temptation of money and power — turn a blind eye to what’s happening around you.
- Bring the truth to light — even if it destroys your career.
- Or find your own path — where there are no right answers, but a chance to stay yourself.
In Zero Sum, there are no “good” or “bad” decisions. Only consequences. And you’ll be the one paying for them.
🎮 Who this game is for
