Overview
Crucial Investigation is a 3D visual novel for players who want a darker, corruption-driven drama with a policewoman lead. The tone stays serious and gradually unsettling rather than lighthearted.
Story
Amy, a young policewoman who genuinely wants to help people, is assigned by her boss to investigate a case tied to a nearby school. What starts as routine police work pulls her into something far more compromising than she expected.
Gameplay
Play unfolds as a text-based visual novel where you follow Amy's investigation through dialogue choices and story branches. As the case deepens, situations shift from straightforward police work into scenes involving corruption, control, and exploitation, with the school and police station both serving as recurring settings for the story's progression.
Features
- 3D character art with animated scenes throughout the story
- Multiple settings tied to the investigation, from the school to police locations
- Branching moments where choices affect how Amy's case — and her situation — develops
Notes
The story includes non-consent, mind control, and coercion themes as central plot elements, not optional side content.
Installation
1. Extract and run.
