by jas.kuberski
corrupt900 [BROKEN] is a horror Forge mod for 1.20.1, built around a main villain that players must defeat to reach the endgame.
What it does
The mod is a horror adventure in which the main objective is to survive and defeat corrupt900, the main villain. Defeating him makes the endgame item, the Source Code, available to craft. The story centers on a world filled with odd-looking pigs and people, and on a head-shaped entity that wants to take over the game.
The author advises turning off Minecraft's music while playing, and says the mod plays better with an older Minecraft texture pack. The mod was made by the author as a horror project, and it also includes a Herobrine-style character. corrupt900 [BROKEN] is released under the MIT License, is not open source, and is published for Forge only. Servers that run it need every player to install it too. Files cover 1.20.1 only, with 1.1 as the latest file, published on 2026-01-28.
