Subnautica 2 Emergency Supply Cache: All Cache Locations and Contents

Updated: 2026-08-064 sections

Emergency supply caches are hidden stashes scattered across the Subnautica 2 ocean, left behind by previous survivors, abandoned expeditions, or precursor activity. These containers hold useful supplies -- food, water, materials, blueprints, and sometimes rare items -- that can be a lifesaver when you are far from base and running low. Finding them is a rewarding exploration activity that pays off in both resources and lore.

Caches are typically found in out-of-the-way locations: tucked in caves, hidden in wrecked habitats, buried in kelp forests, or perched on remote seafloor ledges. They are not marked on any map, so discovering them requires thorough exploration and a sharp eye. Some are brightly colored supply boxes, while others are disguised as natural objects or hidden inside damaged equipment.

The contents of each cache vary. Early caches tend to hold basic supplies like food, water, and titanium. Deeper and more remote caches contain rarer materials, blueprint fragments, and even unique items. Some caches contain data downloads that reveal the story of whoever left them, adding narrative context to your exploration. Always check every container you find, because you never know what is inside.

How to Find Supply Caches

Finding supply caches is a matter of exploration discipline. The most reliable method is to explore every biome thoroughly, checking caves, wrecks, and unusual terrain features. Caches are often placed near landmarks -- a distinctive rock formation, a wreck, or a cave entrance -- so investigate anything that looks out of place. A supply box wedged in a crevice or a locker inside an abandoned habitat is a common cache type.

Use the scanner room to help locate caches. While it primarily detects resources, it can sometimes reveal the presence of containers or wrecks that hold caches. Set the scanner to detect nearby signals and investigate anything unusual. The scanner room's camera drones can also be piloted into tight spaces to scout for hidden containers before you risk a dive.

Listen for audio cues. Some caches emit a faint signal or beacon ping that you can hear when nearby, especially if you are using the right equipment. Watch for visual clues too -- a cache that is partially exposed may catch light differently than the surrounding terrain. At night, bioluminescent organisms sometimes cluster around caches, marking them with an unintended glow.

Keep a mental or written list of caches you have found and their contents. This helps you plan return visits if a cache respawns or if you need a specific resource it contained. Mark cache locations with beacons if they are worth revisiting.

Cache Contents and What to Expect

The contents of emergency supply caches scale with their location and difficulty. Shallow caches near the starting area typically contain basic survival supplies: cooked fish, water bottles, titanium, copper, and common materials. These are a welcome boost in the early game when every resource counts, but they are not game-changing on their own.

Mid-depth caches, found in kelp forests, plateaus, and wrecked habitats, contain more valuable loot. You might find battery packs, copper wire, silicone rubber, blueprint fragments, and sometimes medkits or first aid supplies. These caches often hold data downloads from previous survivors, which reveal useful survival tips and story context. Always read the data logs, because they sometimes hint at the location of other caches or resources.

Deep caches are the most rewarding. Located in deep zones, caves, and near precursor ruins, they contain rare materials like lithium, diamond, and kyanite, advanced blueprints, ion cubes, and unique equipment. Some deep caches hold spare power cells or batteries, which are enormously valuable during long expeditions when your own supplies run low. The risk of reaching these caches is high, but the reward justifies the effort.

Cache Strategy and Survival Use

Emergency supply caches are not just loot boxes -- they are strategic resources that can save your life. When planning a long expedition, note the locations of caches along your route. If you run low on food, water, or oxygen supplies, a cache can be the difference between completing your mission and dying far from home. Treat caches as resupply points, not just bonus loot.

In the early game, prioritize finding caches near your base. The basic supplies they contain accelerate your progression by saving gathering time. A cache with a spare battery or a medkit can be the difference between surviving a predator encounter and not. Check the area around your lifepod and the nearest wrecks first, because early caches are often placed to help new players.

In the mid and late game, deep caches become critical expedition supplies. When you are exploring precursor ruins or mining kyanite at extreme depths, a cache with spare power cells or a repair tool can save your vehicle and your life. Map these caches carefully and plan your routes to pass near them. If you are running low, detour to a cache before pushing deeper.

Finally, remember that caches are finite. Once you loot a cache, its contents are gone, though some may respawn over a long period. Do not rely on a single cache for your survival -- diversify your supply routes and always carry your own backup supplies. Caches are a bonus, not a substitute for preparation.

  • Use caches as resupply points on long routes.
  • Prioritize early caches near your base.
  • Deep caches save expeditions with spare cells.
  • Always carry your own backup supplies.

Frequently Asked Questions

Caches are hidden in remote locations: caves, wrecks, abandoned habitats, and seafloor ledges. They are not marked on any map, so you must explore thoroughly. Use the scanner room to detect nearby signals and investigate anything that looks out of place. Some caches emit faint audio cues when you are close.

Contents scale with location. Shallow caches hold food, water, and basic materials. Mid-depth caches contain batteries, blueprints, and medkits. Deep caches hold rare materials like lithium and kyanite, ion cubes, and spare power cells. Most caches also contain data downloads with story context and survival tips.

Most caches are finite and do not respawn once looted, though some may regenerate contents over a very long period. Do not rely on a single cache for survival. Treat each as a one-time bonus and always carry your own backup supplies. Diversify your supply routes for long-term sustainability.
