Prepare Food and Water
Crafting food and water is critical for survival during long trips away from your base. Reliable supplies of cooked food and clean water help maintain hunger and hydration levels so you can safely explore deeper, more dangerous areas.
| Note! | Keeping backup supplies in your inventory can save your life when exploring distant areas far from your base. ► Drinking Water Guide |

Also Pack Extra Batteries
Make sure to bring several spare batteries before heading out, since you will need them later to power the Research Post outlet. Extra batteries are also useful for keeping essential equipment running during long and dangerous underwater expeditions.
▼See Battery Power OutletUse Tadpole to Travel Long Distance
Use the Tadpole to travel long distances quickly and safely. Its speed and mobility make it ideal for reaching remote locations like the Alien Ruins, helping you explore dangerous areas while conserving supplies and oxygen.
| Note! | Always carry extra power cells before exploring far from your base and keep repair tools handy in case your vehicle takes damage in deep biomes. |

Watch Out for Hostile Creatures
From small but fast predators to massive deep-sea leviathans, hostile creatures can appear with little warning along the way. If you’re grabbed, immediately change direction to break pursuit.
Escape is Better Than Fighting
Leviathans are the largest and most dangerous creatures in the ocean. Trying to fight them head-on is rarely effective and often leads to losing your vehicle, resources, or oxygen supply.
Leviathans GuideHead Towards the Plateau
You will need to head inside the plateau to reach the Alien Ruins, which is located beyond this point, deeper within its natural rock formations.
Travel Faster With Underwater Currents
Take advantage of natural underwater currents and environmental flow patterns. Using currents effectively can reduce travel time, conserve resources like vehicle power, and help you avoid dangerous encounters.
| Note! | Taking this route reduce the risk of encountering aggressive predators that patrol the upper areas. |

Turn Right At the End of the Tunnel
Carefully follow the main corridor until you reach the end of a branching passage, then turn right. You can find the Alien Ruins at the top of the next major chamber beyond this route segment.
Head inside the Research Base
When you reach the abandoned base, go inside and explore it. Make sure to scan the devices inside the base, as this unlocks new blueprints or story data.
