Subnautica: Call of the Void is an upcoming Game Mod for Subnautica. It expands the game's Dead Zone, adding a whole biome to it with new creatures, new mechanics and even new lore.The trailer for the mod can be seen here.
The mod contains examples of:
- Adaptation Expansion: The whole mod can be briefly described as a big expansion to the Dead Zone.
- AI Is A Crap Shoot: The Precursors created some mechanical Leviathans to protect their bases in the Dead Zone from organic ones... problem is they aren't exactly working well.
- Gentle Giant: The currently nameless Leviathans vaguely resembling birds are pacific creatures despite coming from the Dead Zone.
- King Mook: The Mesmer Leviathan is effectively a much bigger and more monstrous version of the normal Mesmer.
