How to get the Tadpole Depth Module (Mk.1)
Answer first
Install Mk.1 at a Modification Station to raise Tadpole crush depth from 250 m to 450 m. Mk.2 is listed at 800 m, but no Survival acquisition route is verified here; check your build and mode before following a location claim.
The Mk.1 data-card landmark varies; use the Ruby blackbox/Needler Nest leads and confirm the route in your build.
Field notes
| Materials | Celestine ×3, Enameled Glass ×2, System Chip ×1 |
|---|---|
| Tools | Modification Station, Tadpole |
| Depth / zone | 250 m → 450 m crush |
Steps
- Cross to Alien Ruins with a Tadpole; scan Modification Station fragments at the Research Outpost.
- Build Modification Station (Titanium + Celestine + Copper per walkthroughs).
- Locate Mk.1 recipe data in the cave/island Celestine route east of the ruins (TechRaptor notes ~40 m north of Blackbox Ruby 2 as one data-card route; Fextralife describes Needler Nest cave on bearing ~165° from the outpost).
- Craft Mk.1 at the Modification Station: 3 Celestine, 2 Enameled Glass, and 1 System Chip. If your UI differs, use its recipe before collecting a deep-run loadout.
Image: Original site diagram based on the listed recipe sources; no game asset - Install Mk.1 from the Tadpole's top upgrade compartment. Mk.2 is listed at 800 m, but GameWith's May 28 guide reports no Survival data card/blueprint and Creative-only crafting; no current Survival acquisition route is verified in our sources, so check the current build before hunting for it.
Version differences and limitations
- The Mk.1 data-card landmark differs between guides. The Mk.2 Creative-only / no-Survival-card claim is from a May 28 GameWith guide, not a September official confirmation; check the current build before relying on it.
