Grassy Plateaus cover vast areas where the seafloor is too deep for Creepvines to take hold. They feature a great diversity of life forms. They are generally one of the first biomes the player encounters in Subnautica.
Grassy Plateaus are characterized by large, pillar-like structures seemingly created from water current erosion, smooth marine plains, and sandy terrain almost completely carpeted with Blood Grass, giving the Grassy Plateaus their distinctive name. While exploring the Grassy Plateaus, it is advised for new players to look around their surroundings more carefully for groups of Biters, and to stay far away from suspicious sand clouds, as Sand Sharks dwell abundantly in this biome. Tiger Plants, another type of hazard, can also be found in this biome.
Here, the player is offered with a great abundance of resources. Besides creature eggs and other common raw materials, Limestone and Sandstone outcrops can be found attached to other rock structures or hidden within the patches of Bloodgrass. This biome also features several small caverns, as well as entrances to the Jellyshroom Cave.
