The Bottom Line: The Alien Ruins are where Subnautica 2 stops being a survival game and starts being a mystery. Every databank entry, every Blackbox, every weird structure — it’s all telling a story if you’re paying attention. Don’t just rush through to collect loot. Read the entries. Piece together what happened here. The environmental storytelling in this game is some of the best in the genre, and rushing past it is doing yourself a disservice.
