Null Cipher

The release date for Null Cipher is July 26, 2026, on PC. Operating out of Station Seven, you play as a codebreaker intercepting signals in a crumbling sector where multiple factions vie for territory while an unrecognized transmission arrives from deep space.

This is a pure logic puzzle game built around manual cryptanalysis rather than automated hints. You will work through 83 specific messages using classical methods like Vigenère keywords, substitution, and columnar transposition to uncover the narrative across five distinct eras. The challenge lies in identifying the unique encryption style of each faction, such as the Corporate Alliance's mechanical scramblers or the Republic's complex 5×5 grids. Progress depends on your ability to spot patterns and frequency distributions to piece together the sector's collapse.

Buy this if you want a focused, cerebral challenge that rewards patient deduction over twitch reactions.
