About This Game

NULL CIPHER

You are a codebreaker at Station Seven, the only signals-intercept post in a contested resource rich sector on the eve of collapse. Multiple factions are fighting over territory with each other and amongst themselves. And from somewhere beyond the region, transmissions are arriving in a cipher no one in this galaxy recognizes.

Real classical cryptanalysis

Substitution — The Kingdom's bureaucratic letter-for-letter swap.

Frequency analysis, common diagrams, patient inference.

Vigenère — The Federation's keyword cipher. Each noble house uses

its own keyword; learning the politics is part of the puzzle.

Columnar transposition — The Corporate Alliance's mechanical

scrambler. The same letters, reordered by a key permutation. Senior

executives use bigger grids.

Playfair — The Republic's 5×5 keyed-grid pair cipher. The hardest

of the classical four. Republic messages are rare; each is a project.

Trifid — The Fifth Power. Unknown to your hint manual until you crack

your first sample. The endgame.

Click a ciphertext letter. Every instance of that letter lights up at once.

Type your guess. The whole page updates simultaneously.

83 hand-authored messages reveal a sector arc across five chronological

Eras — The Stable Order, The Heat Rises, Things Get Strange, The Belt

Collapses, The Witness. Each Era unlocks as you decode half of the previous

one. Within an Era you choose what to crack and in what order. There is no

formal ending; the game finishes when you decide you are done.

Keyboard required. Patience recommended.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:
