For Content Creators:
This Modpack is NOT a Dweller/Broken Script Modpack, The Modpack is more an ARG of The Old Xbox 360 Edition.
Play the Modpack Like It Was, When You Were Playing The Old Xbox 360 Edition When You Were Younger.
Be Patient, The Horror is Slow and Relies more on Atmosphere/Subtle Creepy Events
Enjoy!
Lore:
You have a hobby in discovering lost and unreleased media, you were on a Lost Media Discovery Fourm when a post called: "Unreleased Beta Build of Minecraft Xbox 360 Edition" from a verified user known as: "BlastByte97" catches your attention.
The fourm post reads:
BlastByte97 (OP): hello, i recently accquired an unreleased beta build from one of my very close friends who used to work at 4j studios and worked on the development of the xbox 360 version of minecraft i will be keeping him anonymous for privacy reasons but he gave me the files for an unreleased beta build of minecraft on one of his old working drives he used back in the day to develop the game now that the hard drive is on its last legs he gave me permission to archive and upload the beta build dont belive me here is the link i tested it on my modded 360 and it works have a try

You click on the link which takes you to The Internet Archive and you download the files, upload them to your usb, and plug it in to your modded xbox 360. True to his word it was an unreleased beta build of Minecraft Xbox 360 Edition and you create a minecraft world.
FAQ:
Which Keybind Is "Inventory": The Keybind is "TAB".
Can You Add This "XYZ" Horror Mod To The Modpack: This modpack relies more on: The Atmosphere, Autophobia, Feeling Watched, and Strange/Creepy Occurrences Instead of Cheap Jumpscares and Being Insta-Killed By Dwellers Making Loud Noises.
The Visuals Are Garbage, Fix Them: the visuals are intended to look that way to try and recreate the feel of minecraft on old consoles especially if its themed around an unreleased beta.
Why Is This "XYZ" Feature/Mechanic Not In Here: a bunch of newer features from newer versions were removed to recreate the feel and gameplay of older versions of minecraft, you add them back in the "Nostalgia Tweaks Menu".
This Mod Sucks/I Dont Like It: Consider leaving some Criticism in the comments of what you dislike about it.
