Zero Sum

Zero Sum is a 3DCG animated visual novel for players who like corporate drama mixed with adult content. The tone stays grounded, with tension building alongside the moral cost of every decision.

Story

A testing department manager is unexpectedly promoted to head Project Icarus, tasked with launching an algorithm that raises taxi prices by exploiting user vulnerability. As the project moves toward release, he learns that his promotion was never a reward but a trap in a system where profit and ethics cannot coexist. Someone else already knows what he's doing, and they're waiting for him to slip.

Gameplay

Players guide the protagonist through story-driven choices that shape both the fate of the algorithm and his personal relationships. Decisions carry weight, branching the narrative through animated 3DCG scenes that mix workplace tension with group encounters. Progress unfolds episodically, with each choice from earlier chapters carrying into later ones.
