Porky's Legacy: Era of Corruption

Porky's Legacy: Era of Corruption adds Ominous Valley as a new biome where a new wood type can be found, with flowers, structures and more content placed in the deeper fog. Hazed Plains and other biomes were added in later versions, and the mod changes how mobs spawn based on nearby biomes and dimensions. Deadtime Jones spawns more often in this version, and a fear bar tracks the player's fear, rising and lowering with nearby mobs. Higher fear raises a maximum that the author describes as an event at the end of a run.

The mod is intended for players who want a horror challenge with corruption-themed content, and it works on servers as well as clients. Geckolib is required, so it must be installed alongside the mod. The files cover 1.19.4, 1.20.1 and 1.21.1, and it is released under All rights reserved, so it is not open source. Shaders can break some of its fog effects, so the author advises against using them with the mod.

The Dweller has been reskinned in this version. A corruption mechanic allows corruptinies to spread further by multiplying inside Corrupted Spores. A configuration option enables the Corrupted Plague. The mod also includes an Easter egg that breaks the fourth wall, which does not change the main gameplay.
