Under Signals

Decode the signal. Identify the mimic. Don't let them in.

Description

You are a newly appointed customs inspector at Olympus Station, humanity's furthest outpost. Your job: verify incoming ships by decoding their ARGUS four-quadrant signal — hull ID, status, cargo, and intent.

The military hands you a manual. Half of it is redacted.

Over 5 days, you process incoming vessels using a CRT-style terminal interface. Cross-reference the daily manifest, decode the raw signal data, and submit your assessment. Some ships are exactly what they claim to be. Others... aren't.

Something out there has learned to mimic our signal encoding. It's your job to spot the forgeries — subtle violations in status logic, cargo isolation rules, and warning codes the military doesn't want you to know about.

3 endings based on your decisions:

• 🔴 Port Compromised — Too many mimics got through
• 🟢 The Vigilant Sentinel — You saw through the lies
• 🟡 Blurred Lines — Somewhere in between

How to Play

1. Wait for a ship signal, then download the quadrant data
2. Compare the signal against the ARGUS manual (SOP button)
3. Fill in your decode report: Hull ID, Status, Cargo, Intent
4. Clear or Reject the vessel
5. Pay attention to what's redacted — the patterns are there if you look

Controls

• Mouse only — click to interact with all panels
• SOP button opens the (partially redacted) operator's manual
• LOG button shows your decision history

Theme Connection: "Signal"

The entire game revolves around reading, decoding, and trusting signals. Every ship broadcasts a four-quadrant signal that you must interpret. The mimics forge these signals to pass inspection. The military's redacted manual hides signal patterns you need. Even the narrative builds through intercepted signals — a comms officer's whispered warning, a garbled emergency broadcast, an "accidentally" decrypted MIMIC protocol transmission. The question the game asks: when the signal looks right but something feels wrong, do you trust the data or your instincts?
