Project overview

IF YOU USE THIS MAP OR MODPACK IN A VIDEO PLEASE LINK IT IN YOUR DESCRIPTION! I LOVE WATCHING YOUR VIDEOS :) Playlist of all videos that feature Mosslorn: https://youtube.com/playlist?list=PLLeZSILT0VlzHvRu3VJJcFtsXPZ4T8qdM&si=xnSw8y_7xpiWkaP6 Mosslorn is a solo map project, with a massive 1000x1000 block abandoned city, slowly being consumed by a mysterious moss, with tons of secrets ready to be explored! This is a vanilla+ modpack expanding on the experience for the vanilla map: Mosslorn. It includes some zombie survival mods, backpacks, and general optimization for exploring the desnse overgrown city. What will you find? Ever wanted to scavenge through a city from a civilization long gone?? This map is meant to be played in Survival Mode, with command blocks enabled! You are allowed to break, scavenge, and loot any building or structure, and there is a hidden storyline about what happened to the city, and lore hidden throughout the crumbling buildings! You can play this as a survival experience, or an quest to find all of the hidden secrets. Brief List of things featured in this map: - Hundreds of densely decorated and lootable buildings - Skyscrapers - Toppled skyscrapers - Subway and Tram system that circles the city - Bass Pro Shop Pyramid - Tomboy Outback - Femboy Hooters - Cathedral - Big Library! - Big Statue! - A hidden prison - Top Secret bunkers - Lore hidden around the map - Backrooms? - A particle accelerator?? - AND MUCH MUCH MORE Frequently asked questions (FAQ): Q: Can I use this map for a video/server/modpack? A: Yes of course! As long as you credit me, are not redistributing the world, and not making money off of using it, you can use it however you'd like. If you are republishing the map (like in a modpack or mod) or using assets from it, please contact me to discuss the details before publishing. Q: Why is the map crashing when I try to play it? A: My maps are usually very detailed and large, so they may require you to allocate more RAM to Minecraft, or require the use of optimization mods like Sodium/Lithium to run on slower systems. Q: Can I play this on Bedrock? A: Yes! There is a Bedrock edition port available in the world files folder which can be found on the Mosslorn world project site. Some features may be broken because the conversion between versions is not perfect, the map should overall be the same, but I apologize for any minor details that may be glitched! Q: Can I play this map with added mods? A: Yes! This is intended to be a vanilla survival experience, and the mods that have been added are minor. There should be no issues modding it further, if intended. However, please do not ask me for help regarding modding or editing the map, as it is outside my area of expertise (I just make maps lmao). Q: Why don't the custom player head food/items/tools work? A: They are from a plugin called Slimefun, which is now deprecated for this map. You can ignore these items or use them for their vanilla functions. (Optional) if you want to use the Slimefun items, you can download it here: https://github.com/Slimefun/Slimefun4 Q: Why can't I join your discord? It says the discord link is expired? A: The server link is not expired! We get several people joining every day, however the server is very large so we have anti-alt and anti-bot protection. If you have a brand new account or do not have a profile picture, your account will be automatically banned. Feel free to reach out to me via curseforge or discord dms if you need assistance.

FreeMinecraftMods decision guide

This modpack is most relevant to players looking for Exploration, Multiplayer, Map Based, Horror on Fabric. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.

The source record was updated on Jun 27, 2026. Check the changelog and file page to see whether that update applies to the version and loader you plan to use.

What to verify before choosing a file

• Confirm that the file is published by the credited creator on the linked official source.
• Match the Minecraft version exactly instead of relying only on a broad category label.
• Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
• Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
• Back up worlds and configuration files before testing the project in a long-term save or public server.
