Delta Island

Delta Island is a small above sea level biome in Subnautica: Below Zero, and the location of Delta Station and the Communications Tower.

The biome is surrounded by the Thermal Spires, Purple Vents and Tree Spires. Koppa Mining Site is located underneath the island, with entrances found near its coast.

Description
Delta Island is a small rocky landmass with a dark sediment base and covered in snow. The island is highly weathered, with many fragmented and degraded rock layers present on the surface. The island is populated by several large flora species and Pengwings.

Several hot springs are found here and often contain Crystalline Sulfur. The player will be able to use these along with Thermal Lilies in order to keep their body temperature high.

Trivia

 * Five diamonds can be found on the island. These diamonds are only accessible by using a Spy Pengling to travel through the narrow opening of the tunnel where the diamonds are.
 * Delta Island was originally named Rocket Island.
 * This is due to the fact that the Exchanger Rocket was found on the Delta Island in previous versions of the story.
