This modpack of around 77 mods is aimed towards giving a really hard challenge. But this time, there is so much more, including more passive mobs, biomes, and hostile mobs. The parasites here do not have phases in order to give more spookiness. In addition, there is a progressing difficulty system and some mobs can break through certain blocks. You can try to sneak around most mobs, but if they hear or smell you they will go after you. Enjoy. (Also I do not own any of these mods)
