How to build a Tadpole in Subnautica 2 and all upgrades

Subnautica 2’s guide shows how to unlock the Tadpole by scanning it and reaching the Tadpole Pens area.

Players then need a suitable base with a moonpool, plus the Tadpole Dock and Vehicle Fabricator to build it.

The Tadpole becomes the game’s fastest early vehicle, making travel and exploration much easier.

The guide also covers its upgrade chassis, including the Scout Ray Chassis and Haul Chassis.
