How to reach the Alien Ruins in Subnautica 2, and what you need to do afterwards
Subnautica 2’s Alien Ruins represent a significant progression milestone, marking the transition from the game’s tutorial phase to genuinely challenging content. Located over 600 meters east of the Tadpole Pens, reaching the ruins requires traversing a treacherous expanse of deep ocean that ventures far beyond your starting safe zone.
The journey is perilous, with players encountering dangerous creatures including the Collector Leviathan—a terrifying sea monster that patrols the waters en route to the ruins. This crossing represents the first major traversal challenge in the game, requiring careful preparation and strategic planning to survive the hostile marine environment.
Gaming publications recommend taking specific precautions before attempting the journey. Having your own tadpole companion can significantly improve both safety and efficiency during the crossing, while various preparation steps help reduce resource waste and unnecessary backtracking. Once players successfully navigate the dangerous waters and reach the Alien Ruins, they unlock a new area with additional objectives and materials to gather, furthering their progression through Subnautica 2.
