Field notes
Narrowband Games describes its design aim as making games that reward patience and attention, likening the key clue to a quiet line in the noise. Its sole named game, Thermocline, is described through sonar waterfall readings, narrowband lines, and bearings used to form a firing solution. The homepage says the game is in playtest and lists campaigns from the Red Sea to beneath Arctic ice, but does not detail how to access that test.
