Subnautica 2’s new vehicle chassis is “a dream come true” for its level designers

Unknown Worlds has described the second major Subnautica 2 update, which adds a larger, more threatening region inhabited by the Collector Leviathan. The update matters because it combines new exploration and story details about Proteus and the Axum with a new vehicle that will change how players move through and interact with the environment.

The Seafrog Chassis turns the Tadpole into an exosuit with arms and legs, allowing strong jumps, dashes and climbing. Designers say its movement will support new spaces and puzzles, while caves, structures and environmental clues will help players find resources, learn the setting’s history and avoid danger. The Collector’s four tentacles are independently controlled and physically simulated; friendly Descenders can also signal its approach by staring towards it and hiding.
