The Bottom Line: The Tadpole isn’t just a vehicle — it’s your lifeline. I spent my first few hours treating it like a nice-to-have and wondering why I kept dying in deep water. Then I built one, upgraded it, and suddenly the ocean opened up. Prioritize the Depth Module. Get the Scout Chassis before you cross to the Alien Ruins. A well-equipped Tadpole is the difference between exploring and just barely surviving.
