In Subnautica: Below Zero, the exploration of abandoned Alterra bases and ruins is crucial for uncovering the game’s narrative and unlocking valuable resources. Here’s a detailed guide on how to locate and efficiently explore these sites.

How to Find Abandoned Bases and Ruins

1. In-Game Markers and Satellite Maps:
– As you navigate the ocean, approaching certain islands or underwater areas will trigger map markers that indicate nearby bases. Early in the game, coming near specific islands will display markers for docking facilities and bases. For instance, at Delta Station, you can find satellite maps that highlight locations of other Alterra bases, serving as a roadmap for further exploration.

2. Distinct Environmental Features:
– Keep an eye out for unique geological formations or landmarks. For example, Outpost Zero is situated northeast of your starting Drop Pod and can be accessed via an underwater cave located near a field of brinicles—ice formations that resemble icicles. Following these brinicle formations along the glacial wall will lead you to the cave entrance that provides access to the base.

3. Specific Biomes Known for Alterra Sites:
– Certain biomes are particularly rich in abandoned Alterra technology and structures. The Twisty Bridges is a notable region filled with hidden tech sites and ruins, providing ample opportunities for discovery and loot. This biome is just one of many that can yield valuable locations for players to explore.

Tips for Exploring the Bases and Ruins

1. Follow Light and Environmental Cues:
– Many abandoned bases feature visual cues like light sticks directing players to their entrances. For example, within Outpost Zero, once you traverse the underwater cave, look for light sticks that illuminate the path leading into the base, aiding in navigation.

2. Prepare for Cold and Depth:
– With bases frequently located within harsh cold environments and deep waters, it’s essential to upgrade your equipment to endure low temperatures and manage deep-water pressure. Equip yourself with thermal suits and adequate diving gear to ensure safe exploration.

3. Unlocks and Story Progression:
– Investigating these locations can yield vital upgrades and narrative elements that enhance gameplay. Early exploration of Outpost Zero can equip you with useful technology and offer critical story clues, propelling your adventure forward.

Notable Base Locations to Explore

– Outpost Zero: Located northeast of your Drop Pod and accessed through a cave surrounded by brinicles.
– Delta Station: Offers a satellite map that reveals additional bases, making it an important early-game location.
– Alterra Tech Sites in Twisty Bridges: Rich in hidden tech and ruins, this biome contains various exploration opportunities.

Summary

To maximize your exploration of abandoned bases and ruins in Subnautica: Below Zero, utilize in-game map markers, environmental indicators like brinicles and light sticks, consult satellite maps when available, and focus your exploration on biomes such as the Twisty Bridges. Ensure that you are adequately equipped to handle the rigors of cold and deep-water exploration, which are crucial for successful and safe navigation through these sites.
