I plunged into Subnautica 2 Early Access and can't wait to go deeper
Subnautica 2 retains the underwater survival formula of its predecessor while introducing a new colonization mystery, more reactive marine life, flexible base-building tools, improved visuals, and cooperative multiplayer. The early-access build offers roughly 20 hours of exploration and more for dedicated builders, but objective progression can be unclear, frequent base-status voice prompts become irritating, and performance on Steam Deck needs optimization. Its story shows promise through themes of rogue artificial intelligence, alien adaptations, infection, and ecological instability. Fans of the original may enjoy playing now, while players seeking a complete narrative should wait for the full release.
