Overview

Bio-Unit is a 3D dating sim and trainer for players who want a darker, sci-fi take on power and control. The tone is clinical and cold, with romance framed as something managed rather than freely given.

Story

Working for Neogenesis Corp., you take on the role of Operator, tasked with supervising a Humolunco — a biological weapon built in human form — and guiding her toward what the company calls the Perfect Form. Every protocol you complete and every limit you push shapes her abilities and her mind, while the corporation watches and records your every decision.

Gameplay

You manage the unit's training and emotional state through choices and resource decisions, balancing her development against the demands of the corporation. Combat sits alongside the trainer systems, with the unit's abilities tested directly rather than left as background stats. Progress depends on how you treat her — as a tool to refine, or something closer to a person.

Features

Female-led combat and domination themes woven into the trainer structure
Customization options for the unit's appearance and form
A corporate framing device that keeps every choice under surveillance
3DCG presentation built around a single evolving character

Installation

Extract and run.
