False Flag is a radio intelligence thriller, inspired by Papers, Please!

You are an operator at the receiver, and every transmission is a test.

Enemy forces have learned to forge your army's callsigns, auth codes, and duress signals. Your job: separate the valid messages from the forgeries.

15 Minutes Playtime, Start to End.

How it works

Each shift, transmissions arrive one at a time. Read the message, then verify it with the tools at your station:

• Decode - crack the cipher to reveal the true body
• Signal Analysis - tune the frequency and pull the real signal out of the noise
• Map Board - check whether the claimed position holds up
• Codebook - your reference for what a genuine message looks like
• 3 Minute Days - Each day lasts 3 minutes, and new days bring in new tools to use

Then make the call: Pass On or Reject.

Pass a false flag, and enemy disinformation flows to command. Reject a genuine message and real intel is lost. Over the campaign duration, learn more tools and distinguish the incoming messages to the best of your ability.

Jam Notes: My first upload was within the time limit, but I had issues with Runtime reflection that I tried to fix, so the first upload did not work. I have kept it below for the sake of providing clarity. I have uploaded a fixed Windows version, as well as a playable web version, within 2 of the 48 hours allowed for bug fixing.
