Catacomms: a dungeon on radio

Field notes

Catacomms makes radio bandwidth part of the game design rather than hiding it behind a network layer. The page describes a deterministic room engine, retransmission and acknowledgement over packet loss, and eight-byte result hashes that expose divergent game states. Expeditions are jointly signed by the players present, while a solo run is signed only by its player and produces no shared board result. The stated item system combines 29 shapes with 14 colours.
