Before the area was removed a Shadow Leviathan and a few crystals could be found at the entrance to the area. The area was removed from the world as of build 32522 and the crystal wall has been replaced by a short tunnel leading to a dead end.
It was then cut as the story no longer required that the player be kept from accessing the Architect Gate Base (formally known as the Architect Shield Base). In early access version 8 and 8.1 the entrance to the area was blocked off by a wall of crystals to stop the player from progressing further than the developers intended. The biome was one of the three original 'Hover' biomes, the other two being the Glacial Basin ( hoverarea) and the Arctic Spires ( hoverzone2). It had no fauna and was connected to the Fabricator Caverns via a big deep hole. Hoverzone 3 was an unfinished surface biome that served as the way back to the Architect Gate Base (which at the time was known as the Architect Shield Base) during the game's final act. 12.5 Seatruck Energy Efficiency Upgrade.10.3 Alterra All-Environment Protection Suit.
