Mofu's subnauticraft
This small project plans to add all of the subnautica's leviathan in minecraft, starting with the reaper leviathan
⬇ Download on Modrinth
As a celebration for the early access of subnautica 2, i wanted to make a small project that adds all of the first game's leviathan with the first one being the reaper leviathan
as of now the mod contains the reaper mob, that can spawn in most deep oceans. a craftable seamoth and a statue as a trophy if you get to kill the guy and thats it.
the reaper has its own unique AI and set of attacks, and a "jumpscare" if the player gets attacked when low enough. they spawn in all of the deep ocean biomes
pls report any bugs in the comments, and if you wish for me to continue this small project.
WARNING TRUE SIZE COMMAND CANNOT BE UNDONE, BUT CAN BE LOCKED/UNLOCKED IF U WANT
I also made a youtube video on the process of making the mod and why i made it. https://www.youtube.com/watch?v=gzaYuvKlcoQ
