In this video, we’re going to be exploring a DLC-sized Subnautica mod that literally adds two new biomes to Subnautica along with adding new elements to the game’s story, introducing new flora, fauna, and leviathans, and adding new equipment and base pieces each of which can be constructed with the many new resources now found throughout the Crater. The amount of new content this mod adds to the game is honestly jaw dropping so without any further ado, let’s dive right in... ►Follow my socials: https://linktr.ee/speedymouse More content: ►Best of SpeedyMouse:    • Best of SpeedyMouse   ►Subnautica Mods:    • Subnautica Mods   ►Gargantuan Leviathan Mod:    • Gargantuan Leviathan Mod (Subnautica)   All the mods in this video were created by Reika and are available to download below.
