The Corrupted Code.jar
The Corrupted Code is a Forge horror mod for 1.20.1 in which a forgotten world's reality becomes intertwined with the game's code, and the story unfolds gradually as strange events begin to occur.
What it does
The story begins years ago, when a mysterious developer started an experiment that never finished. The first hours of play look ordinary, with peaceful villages, bustling mines and no sign that anything is wrong. As time passes, inexplicable phenomena appear, the world changes little by little, and entities begin to emerge as the corruption spreads. Some of them watch from a distance while others pursue goals no one fully understands, and each encounter reveals another piece of the mystery.
The server and every player need the mod installed. Only Forge 1.20.1 files are published, the latest being 1.0.1 for 1.20.1, and the story is written for players who read English at an intermediate level; the author recommends it for children aged 14 and over. The Corrupted Code is not open source and is licensed as All rights reserved.
