Subnautica 2 Tadpole Depth Module
Subnautica 2 GuideA version-aware guide for one of the most searched upgrade paths.
Quick answer
Current guide evidence points to a station split: build the Tadpole through the vehicle setup path, then craft found Tadpole module upgrades such as the Depth Module at the Modification Station before slotting them into the Tadpole upgrade compartment.

Route cards
Unlock the vehicle first
The Tadpole has to exist before the depth module matters.
- Finish the Tadpole progression path first.
- Treat the module as a later install step.
- Check the current blueprint panel after patches.
Craft at the right station
Module-style upgrades belong to the Modification Station path.
- Do not expect the Vehicle Fabricator to install the module.
- Gather the required materials only once the station is ready.
- Keep the route short and controlled.
Install and push deeper
Depth is the first priority for safer deep-biome routing.
- Slot the module into the Tadpole upgrade compartment.
- Use it to extend the next objective loop.
- Add utility modules later when stability is solid.

Where to Find It
- Unlock and build the Tadpole first; depth upgrades only matter once the vehicle is available.
- Progress toward the Alien Ruins / Research Base route where current guides place the Modification Station unlock path.
- Check the in-game blueprint panel after every Early Access patch because station requirements and material costs can shift.
How to Use It
- Craft the module at the Modification Station after you have the blueprint and materials.
- Install the finished module from the Tadpole upgrade compartment rather than expecting the Vehicle Fabricator to equip it automatically.
- Treat depth as the first priority for deeper biome routes, then add utility modules once repair and power margins are stable.

FAQ
Is Tadpole Depth Module available in Early Access?
Yes, module progression is referenced in current guide coverage, but exact tiers can vary with updates.
Do I craft it in the Vehicle Fabricator?
No for module-style upgrades in the current guide flow: use the Modification Station, then slot the module into the Tadpole.
What usually blocks this upgrade?
Missing advanced materials, incomplete Tadpole progression, or not having the Modification Station ready.
Why are guides inconsistent?
Subnautica 2 is actively patched in Early Access, so routes and requirements can drift quickly.
