Subnautica 2 Colonist Bunkers Guide: Locations and Upgrades

The four discovered colonist bunkers offer crucial enhancements to your biobed setup, directly boosting your player capacity. Forget needing to constantly backtrack to upgrade your core base—these specific locations provide immediate, powerful boosts that allow for deeper gameplay customization right when you need it most. Understanding exactly where to find colonist bunkers is the key to maximizing your utility.
Locating the Four Colonist Bunkers

The developers have strategically placed these bunkers to ensure players explore various zones, rewarding curiosity with vital upgrades. Knowing the exact coordinates will save you hours of searching in the deep ocean trenches.
Anita's Garden (Endurance Boost)
Located approximately 100m ESE from the Lifepod, Anita's Garden is one of the most straightforward stops. This bunker focuses heavily on expanding your Endurance, granting a substantial +3 inventory slot boost. This is crucial for stockpiling rare materials and equipment.
Quaker's Meetinghouse (Endurance Boost)
Head 250m SSE to Quaker's Meetinghouse. Like Anita's Garden, this site provides a major boost to Endurance, granting another valuable +3 inventory slot capacity. Finding both of these bunkers is key to achieving maximum resource storage.
Salvage Site (Dexterity Focus)
For those who need more versatility than just storage, the Salvage site, located around 200m NNE, is your target. This bunker prioritizes Dexterity, giving you a much-needed +1 tool slot/keybind. This boost is critical for streamlined interaction with the environment, allowing you to carry specialized tools alongside your primary gear.
The Fourth Bunkers Location (Endurance Boost)
A fourth, unlisted bunker is situated further out at 300m SSW. This site provides a final, powerful boost to Endurance, granting a third substantial +3 inventory slot upgrade. These bunkers are essential for managing resources and tools more efficiently, ensuring you never feel constrained by your current biobed capacity.
Optimizing Capacity and Tool Functionality

The true value of these bunkers lies not just in the numbers, but in how they fundamentally change player flow. The ability to increase inventory capacity (Endurance) is vital for collecting materials and storing equipment, allowing you to traverse larger areas without panic-scavenging.
Equally important is the boost to Dexterity. While more storage sounds good, having extra tool slots allows for greater versatility. It means you can carry specialized mining equipment, crafting components, and utility tools simultaneously, streamlining your interaction with the environment. These upgrades are the core of a successful subnautica 2 colonist bunkers walkthrough.
The goal is simple: Use the Endurance boosts from Anita's Garden, Quaker's Meetinghouse, and the SSW bunker to maximize storage, then visit the Salvage site to ensure your toolset can keep up with your expanded capabilities. Mastering these upgrades means you are equipped for any challenge the deep ocean throws at you.
Strategic Resource Allocation

The bunkers encourage players to map out their journey efficiently. Instead of viewing them as isolated points, consider them part of a resource circuit. By visiting them in a strategic order, you maximize the benefit of your time and limited oxygen supply. Remember that each bunker’s reward is tied to a specific stat—Endurance for general capacity, and Dexterity for specialized tools. This thoughtful approach to colonist bunkers biobed upgrades is what separates casual play from true mastery.
By prioritizing these upgrades, players can drastically improve their overall efficiency, ensuring they can gather materials and store equipment without the constant threat of running out of space. This detailed knowledge of where to find colonist bunkers is your blueprint for surviving the most demanding biomes in the game.
As the narrative unfolds, subsequent content may require even more specialized tools and larger caches of rare materials. Therefore, optimizing your base capacity and toolset now will give you a massive edge in the coming zones.
Watch a detailed walkthrough of the new bunker locations and upgrades.
Looking ahead, we anticipate that further biomes will require not just more storage, but entirely new power sources for the biobed itself. Keep an eye on developer updates for potential new types of specialized utility upgrades, perhaps focusing on oxygen regeneration or advanced crafting station expansion.
We also predict that the final, most powerful colonist bunkers will require advanced crafting materials found only in the deepest, most dangerous parts of the map, forcing players to master advanced survival mechanics.
Ultimately, the game loop suggests that optimizing the base will become a continuous process, making the knowledge of all existing colonist bunkers a critical survival skill.
