Subnautica 2 Audio Logs & PDA System Guide 2026

PDA System Overview

The PDA (Personal Digital Assistant) is your central interface in Subnautica 2, serving as inventory, crafting menu, lore archive, and navigation tool all in one. Understanding its organization is essential to playing efficiently. The PDA is divided into several tabs: Inventory for items and equipment, Blueprints for craftable items and their material requirements, Log for story tasks and radio messages, Databank for scanned lore entries, Creatures for the bestiary, and Collectibles for black boxes and special items. Each tab updates automatically as you scan, craft, and discover.

The Blueprints tab is your crafting roadmap. It shows every unlocked blueprint organized by category, with material requirements and crafting location. Blueprints you have not yet unlocked appear as silhouettes with hints about where to find the fragments. Use this tab to plan your resource gathering: check what materials a desired item needs, then target biomes that contain those materials. The tab also shows which blueprints require a specific fabricator or station, helping you plan your base layout.

The Log tab tracks story progression, displaying active and completed PDA tasks, radio messages, and story beacons. Review this tab regularly to ensure you are not missing a critical objective. The Log also records discovered locations and key events, serving as a progress journal. If you ever feel stuck, checking the Log for uncompleted tasks usually reveals the next step. The PDA's organizational structure is designed to keep you informed without overwhelming you, and mastering its tabs is the key to efficient play.

• Inventory: Items and equipment management
• Blueprints: Crafting roadmap and material requirements
• Log: Story tasks and radio messages
• Databank: Scanned lore entries and encyclopedic data
• Creatures: Bestiary and scan progress
• Collectibles: Black boxes and special items

Audio Logs: Finding and Playing

Audio logs are voice-recorded entries left by previous inhabitants of the planet, and they are the primary vehicle for narrative delivery in Subnautica 2. Unlike text-based databank entries, audio logs play voiced recordings that immerse you in the story. They are found in wrecks, abandoned bases, lifepods, and precursor facilities, typically as interactable data pads glowing with a soft light. When you approach one, a prompt appears to download and play the log.

Downloaded audio logs are stored in the Databank tab under an Audio subcategory, where you can replay them at any time. New audio logs trigger a notification and often advance the story, adding tasks to your Log tab or revealing new beacon locations. It is good practice to listen to each audio log fully the first time you find it, because the narrative context often contains clues about where to go next or what threats to expect. If you miss something, the Databank lets you replay logs with accompanying text transcripts.

Audio logs are distributed across all depth tiers, so you will collect them progressively as you explore. Shallow wrecks contain early logs that establish the premise, while deep precursor facilities hold the logs that reveal the central mystery. There are approximately 35 audio logs in the game, and collecting all of them is not required for story completion but enriches the narrative significantly. Unlike black boxes, audio logs are often integrated into story progression, so you will naturally collect most of them by following the main objectives. For completionists, the Databank tracks which logs you have found and flags missing entries.

Databank and Lore Management

The Databank is your lore archive, storing every scanned entry from flora, fauna, objects, and story elements. Each time you scan something new, a databank entry is created with encyclopedic information: biological classification for creatures, material properties for resources, and historical context for ruins and equipment. The Databank is organized by category, making it easy to find specific entries. For story-focused players, the Databank is a treasure trove that rewards exploration with deep worldbuilding.

Managing your Databank is straightforward but benefits from regular review. After exploring a new biome, check the Databank for new entries to absorb the lore context. Many entries contain hints about resource locations, creature weaknesses, or story clues that are easy to miss if you do not read them. For example, a creature's databank entry may note that it is repelled by a specific tool, or a material entry may mention which biome it is found in. Reading the Databank makes you a more informed and effective explorer.

The Databank also tracks your scan completion percentage across categories. Reaching milestones of 50, 75, and 100 percent unlocks cosmetic and functional rewards, incentivizing thorough scanning. If you are aiming for 100 percent, use the Databank to identify unscanned entries; each entry lists its general location, guiding you to biomes you may have underexplored. The Databank completion goal pairs naturally with black box collection and bestiary completion, giving completionists a clear set of long-term objectives that take them to every corner of the map.

PDA Tips and Efficiency Tricks

Several PDA tips improve your gameplay efficiency. First, use the Blueprints tab to pre-plan resource runs: before exploring a biome, check which blueprints you want to unlock and note their material requirements, then target biomes that contain those materials. This prevents aimless gathering and ensures every trip has a purpose. Second, pin frequently needed blueprints to your HUD using the pin feature, so you can see material requirements without opening the PDA.

Second, use the Scanner Room in tandem with the PDA. The Scanner Room can be configured to highlight specific resources or creatures on your HUD, and the PDA's Databank provides the context for what you find. Set the Scanner Room to track a resource you need, then check your PDA Blueprints to confirm you have enough materials for your target item. This combination of scanning and planning is the most efficient way to gather materials.

Third, keep your Inventory organized using the PDA's sorting feature. Sort by category to group similar items, making it easier to find what you need during crafting. Use waterproof storage containers at your base to offload excess materials, keeping your personal inventory lean for exploration. Fourth, review your Log tab after every story event to catch new tasks and beacons. Players who skip the Log often miss critical objectives and wander aimlessly. Finally, treat the PDA as your companion throughout the game; it is the single most important tool for staying organized, informed, and on track.

For co-op players, remember that blueprint unlocks sync across the team, so the Blueprints tab reflects the group's collective progress. However, audio logs and databank entries are per-player, so each teammate must scan and collect their own lore entries. Coordinate scanning duties to avoid redundancy, and share lore discoveries through voice chat to enrich the group's narrative experience.
