Scary Ambiance is a Minecraft Client-Side Modpack based on Fablously Optimized by robotkoer with some ressource packs, shaders and ambient sounds to scare you.

The fact the Modpack is just Client-Side makes it able to play on any public server, but I do not assure you that all mods are allowed on any server.

When you don´t just want a scary ambiance I highly recommend you to play the Horrorgames Modpack.
