To find the alien bases, head to the deep! Start by exploring the Degasi Seabases in the Jellyshroom Caves and the Grand Reef. From there, follow signals and clues to deeper biomes like the Lost River and the Lava Lakes. Don't forget to upgrade your gear!
Trust me, you’ll need to prepare. The Deep Grand Reef, Lost River, and Lava Zone – those alien bases lurk way down there. Ensure your submarine is ready for some serious depth exploration!
Go deep, my friend! Alien bases are hidden in places like the Lost River and the Lava Zone. Just make sure you have a depth module for your Seamoth or Prawn Suit.
They’re everywhere in the deep parts of the game! Look for the Lost River and the Inactive Lava Zone.
