How do I build a base that is safe from underwater threats in ARK: Survival Evolved?

Building a base that is safe from underwater threats in ARK: Survival Evolved requires careful planning, resource management, and an understanding of the game's mechanics. Underwater threats include aggressive creatures like Megalodons, Electrophorus, and even other players in PvP scenarios. To create a secure underwater base, you need to consider location, materials, defenses, and utility.

First, choose a safe location. Not all underwater areas are equally dangerous. Look for spots with fewer aggressive creatures, such as shallow waters near the coast or areas with natural barriers like rock formations. Avoid deep ocean biomes where large predators like Mosasaurs and Tusoteuthis roam. A good example is the Hidden Lake on The Island map, which has a nearby underwater cave that can be fortified. Alternatively, consider building near underwater resource nodes like oil veins or silica pearls, but ensure the area is defensible.

Next, gather the necessary resources. Underwater bases require a lot of materials, especially metal and crystal. Metal is essential for crafting durable structures, while crystal is needed for windows and certain advanced items. Use a metal pickaxe or an Ankylosaurus to mine metal nodes, and gather crystal from caves or mountain tops. You will also need cementing paste, which can be crafted from chitin/keratin and stone or harvested from beaver dams. Polymer is another important resource for advanced structures, which can be obtained from killing Kairuku or harvesting organic polymer from certain creatures.

Start by building a foundation. Underwater bases require stone or metal foundations to prevent damage from creatures. Wood is not recommended as it is easily destroyed. Place the foundation in a flat area of the ocean floor, ensuring it is stable and level. Use pillars to support the structure if the terrain is uneven. Once the foundation is set, build walls, ceilings, and doors to enclose the base. Metal structures are the best choice for durability, but stone can be used if resources are limited.

To protect your base from underwater threats, add defensive measures. Place Plant Species X turrets around the perimeter to deter aggressive creatures. These turrets require fertilizer and a water source, so plan accordingly. You can also use underwater mines or spike walls to create barriers. Taming aquatic creatures like Megalodons or Basilosaurus can provide additional protection. These creatures can patrol the area and attack intruders. In PvP, consider adding Tek Turrets or heavy turrets for advanced defense.

Power and utility are crucial for an underwater base. Use electrical generators or solar panels to power essential items like fabricators, refrigerators, and turrets. If you are in deep water, consider using underwater air pockets or placing air tanks and scuba gear in the base for easy access. Water wells can provide a steady water supply for irrigation and Plant Species X turrets. Storage is also important. Use vaults or large storage boxes to keep resources safe and organized.

Common mistakes to avoid include building too close to aggressive spawns, using weak materials like wood, and neglecting defenses. Always scout the area thoroughly before building, and ensure your base is well-protected. Another mistake is underestimating the resource requirements. Underwater bases are resource-intensive, so gather materials in bulk before starting construction.

Advanced techniques include using Tek structures for enhanced durability and functionality. Tek forcefields can provide additional protection, while Tek generators offer a reliable power source. You can also use underwater caves as natural fortresses, but be aware that some caves have high-level creatures and environmental hazards. In PvP, consider building hidden bases or using camouflage techniques to avoid detection.

For solo players, focus on smaller, more manageable bases. Use tamed creatures for protection and resource gathering. In tribes, assign roles to members, such as resource gatherers, builders, and defenders. Coordination is key to building and maintaining a secure underwater base.

In summary, building a safe underwater base in ARK: Survival Evolved involves careful planning, resource gathering, and strategic defense. Choose a safe location, use durable materials, and implement strong defenses to protect against underwater threats. Avoid common mistakes, and consider advanced techniques for optimization. Whether playing solo or in a tribe, a well-designed underwater base can be a secure and functional hub for survival and progression.
