Point it at anything you can see. A hooded god on the far side of the universe answers with an atomic beam, and your world gets a crater and a mushroom cloud.
A long 75-hour psychological horror descent takes its time, pays attention to your habits, and uses your world against you. Warning: your world can be deleted for good by the ending in singleplayer. Switch that off in the config.
Makes mobs tougher: zombies dig and build, skeletons lead their shots, and creepers blast through obstacles. Each feature can be toggled in the config.
A discontinued, unstable horror mod with slow world changes, hallucinations, and fake glitches. Use a disposable world: the final event can delete the save.
