Shattered Command

Shattered Command is a legendary horror addon designed to scare you, break your game, and eventually kick you out entirely. The madness creeps in slowly with this addon; while the events are randomized, they escalate the longer you play.

In my experience, it all started with a light mist, similar to a classic Herobrine event (who is actually featured here as well). Then, I began hearing voices and unsettling sounds. At some point, the fog grew heavier and took on a crimson hue. The addon even started changing my game mode constantly, and the Main Menu button completely disappeared...
