Overview

About this game

Heads-up (Work-in-Progress)

This page reflects an early prototype. Many screenshots and clips will look rough. I’ll keep this page updated as core systems, UI, and art progresses. Thanks for checking it out—and please wishlist if you’d like to follow development.

The Night Shift

You take the night shift at the checkpoint in front of Subnet 13.
Hired by a massive corporation, you sit in a small control booth deciding who gets to enter the secured sector. You need the job to survive — and to the company, you’re easily replaceable. Mistakes are costly; one wrong decision could end your career… or worse.

Every Night Brings New Rules

Each night, new regulations arrive: new rules, new procedures, new ways to check the people arriving by metro.
Some nights it’s simple ID verification, other nights it’s cyber-implant monitoring, luggage scans for contraband, interrogations, or blood tests for dangerous infections.
Meanwhile, the data streams never stop — and you must avoid being hacked during transfers.
You decide who passes and who doesn’t.
Not everyone will take your decision quietly.

Under Pressure

The corporation demands quotas, audits, and smooth throughput.
Deep scans take time — do you perform every check and risk missing your quota, or let someone through who shouldn’t be there?
As the nights go on, strange incidents begin to happen: activists, armed civilians, and unexplained signals — events with no corporate protocol to follow.
How will you respond when the system starts to break down, and what will you do when it turns its eyes on you?
