While this module might be limited in usefulness by its dependence on very late-game materials, it is unmistakably helpful in the game’s closing hours. This upgrade works with any area above 30* celsius and has a version that applies to your smaller vehicles as well (although each is a separate blueprint you need to discover in the world.) The Thermal Reactor Module allows players to recharge their submarine by simply parking above intense heat sources like thermal vents or magma lakes. You won’t have this module until very late in the game, but once you grab it, your Cyclops gets quite a meaningful upgrade. Once you find the MK1, you automatically unlock blueprints to craft the others. If you need help hunting them down, the Cyclops Depth MK1 upgrade is located in the Blood Kelp Zone, the Dunes, and close to the border between the Grand Reef and Kelp Forests. Just trust me, you need them, so go find them. Hull Depth Upgrades are vital to progress into the game's end locations but don't give any additional tactical value, so discussing them is moot. NOTE: We will not discuss Hull Depth Upgrades, even though they are essential while playing Subnautica. If you want to range across Subnautica’s beautiful and dangerous map without fear, consider looking into the various upgrades on this list, as they will clue you in on several ways to make the mighty Cyclops even mightier. It has room for some improvements, and the world is laden with beneficial upgrades that can make you the true king of the sea. The truth is, your Cyclops is powerful and incredible but hardly invincible. That may be true until you run out of power in Leviathan waters, and a Reaper shreds your submarine to pieces.

As if all her secrets are within reach and her dangers are at bay.

Once you’ve unlocked and built your first Cyclops in Subnautica, you might feel like the ocean is your oyster.
