broken_code.jar
by pifxl
broken_code.jar, a horror-driven Forge mod for Minecraft 1.20.1, blurs the line between the game and a glitch that spreads through its own world.
What it does
The mod starts with small corruptions: textures go missing, blocks disappear and the world begins to feel wrong. Over time these grow into fully formed entities that stalk and hunt the player. The story is built around the idea that the player is no longer surviving against mobs, but against the code itself.
The mod also reaches outside Minecraft. It can create text files on the desktop, open pop-up windows and show information about the PC. It is client and server, so the server and every player need it. Forge is the only loader, and the mod is for 1.20.1 alone. The mod is all rights reserved and is not open source, and its creators ask that the bundled song not be used without permission.
The author recommends singleplayer. Multiplayer behavior is not confirmed, and the mod does not work with Optifine. It was tested with Embeddium and Oculus, where shaders worked, though only two mods are listed as compatible with shaders.
