  • Become a master code breaker one step at a time - It is not beyond anyone to figure out what a secret message says armed with the right knowledge and tools.

Coming July 31, 2019!

I will be releasing it on Steam for free!

Why free?

I won’t be able to get as much user experience testing done as I would like. It won’t be as refined as my last game Future Proof. So I don’t feel like I can justify charging for the game. Bugs will be minimal and should be hopefully be all ironed out.

Resources for crypt-analysis:


  • The name Room 40 comes from the British cryptanalysis group that was formed in 1914. They broke one of the most influential message of WWI. It was a German message to Mexico to enlist them to join their side and attack the US. Britain leaked this information and managed to bring the then neutral US into the war, shifting the tide of the war.

  • The zodiac killer ciphers. The game takes place in the US in the 60’s around the same era as the notorious ciphers.
