Subnautica Internal Modules
by afkplayin
Subnautica Internal Modules is a NeoForge decoration mod for 1.21.1 that adds a Fabricator First Aid Kit and a Fabricator Radio Wall Cabinet, with the rest of its content placed as decorative blocks.
What it does
Most of the added blocks are decorative, and the Wall Cabinet is the one piece in the set that is not. The mod adds items from the Subnautica setting, such as the Fabricator First Aid Kit and the Fabricator Radio, to a world built on the 1.21.1 release. Titanium and copper can be mined from limestone outcrops, which are harvested with a stone pickaxe.
Installation covers the server and each player's game. Files are published for NeoForge only, for 1.21.1. The author has noted that the model orientation of some blocks is reversed, so they face the opposite direction when placed. The text is available only in English, and the author states the mod was built with a friend and translated with Google Translate.
