Tadpole

Beyond swapping its chassis, the Tadpole takes upgrade modules that decide how deep and how long you can push it.

Confirmed Modules

  • Depth Module (Mk.1 / Mk.2): raises the Tadpole's crush depth so you can dive into the deeper biomes safely.
  • Cavitation Muffler: quiets the sub for a stealthier approach past hostile creatures.
  • Engine Efficiency: cuts power draw so a charge lasts longer.
  • Photovoltaic Charger: trickle-charges the Tadpole in daylight near the surface.
  • Strike Armor: adds damage resistance for hostile waters.

Slot the modules to match the dive: depth and armor for the deep biomes, efficiency and charging for long-range exploration.
