IslandGen
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.21.1 on NeoForge. On other versions it may install and then do nothing.
This mod randomly generates Islands throughout the world. Not your simple prebuild survival island.
Features:
- Random Generation
- Starter hut
- Loot Barrels spawning in the ocean (making it seem like loot from wrecked ships)
- Hidden rooms with loot on islands (Configurable)
There is no Stronghold, but there is a portal. You just need to find it. Who knows, it might just be under your nose. :)
More will be added in future updates!
