A large multi-crew submarine confirmed for Subnautica 2's Early Access roadmap — the spiritual successor to the Cyclops from the original Subnautica. Designed to serve as a mobile base for longer expeditions, supporting up to 4 players simultaneously. Not available in the EA 1.0 launch build; recipe, stats, and blueprint location are unknown. The Tadpole remains the only craftable submersible in EA 1.0.
