# game.shared KESSREL LINE's one shared surface: the game's constants (world frame, palette, fonts, unit kinds and index ranges, regiments, stances, abilities, waves), the event bus every slice talks over, the `battle` state the sim writes and everyone reads, the `audio` and `screens` contracts other slices bind, and the spoken lines with their text. ```lua local K = require("game.shared") K.on("battle.wave", function(p) print(p.wave) end) K.emit("cmd.move", { ids = { 1, 2 }, x = 0, z = 40 }) K.say("wave_1") ``` The design spec at `/zero/source/design/spec.md` says which slice owns which part of it. Nothing here writes a unit, a screen or a sound; it is the place they agree.
