A structural reinforcement module that increases the Tadpole's crush depth from 250m to 450m, unlocking the vast majority of the EA 1.0 map including the Needler Nest, Root Canyon, and the Karakorum Power Plant. This is the single most important upgrade in the early-to-mid game and is essential for completing the main story. Blueprint found in the Observatory biome cave under the Needler Nest (~1,411m ESE of Lifepod at approximately -200178, 450282, -29629).

Notes

Effect: Tadpole crush depth raised from 250m to 450m.

Tips:

  1. This is the highest-priority Tadpole upgrade — get it before attempting Root Canyon or the Karakorum Power Plant.
  2. Blueprint is located next to the [tadpole-haul-chassis-haul-rig] blueprint in the Observatory biome — grab both on the same dive.
  3. Does not stack with Mk.2 — only install one depth module at a time; Mk.2 supersedes Mk.1.
