A new developer vlog for Subnautica 2 has finally given fans their first real look at gameplay, offering a sneak peek into updated features, revamped mechanics, and an early glimpse at alien environments. The latest update from Unknown Worlds confirms the game is still on track to launch in early access later this year, although a precise release date remains under wraps.
This long-awaited sequel to the beloved underwater survival game brings big changes. Most notably, Subnautica 2 will introduce multiplayer for the first time, letting players team up to explore a brand-new alien world. Solo exploration remains fully supported, giving fans the freedom to choose how they want to experience the game.
In the recent dev vlog, Design Lead Anthony Gallegos breaks down some of the exciting changes coming in Subnautica 2. While the video doesn’t show much of the game’s environments, it highlights several core gameplay upgrades—including major improvements to base building. Builders can now look forward to support pillars, superconducting foundations, and new modular compartments that offer more creative freedom and structural integrity than ever before.
Alongside these additions, the vlog teases new tools and systems that deepen the survival experience. The visual upgrade is also clear, with improved lighting, terrain detail, and underwater ambiance, enhancing immersion and atmosphere in every dive.
The teaser trailer released last year (watch it here) first sparked excitement with its promise of a fresh world, compelling narrative, and dangerous new creatures. Now, with gameplay officially revealed, fans are more eager than ever to plunge back into the depths.
Subnautica 2’s early access release is scheduled for later in 2025, and developers have assured the community that feedback will shape the game’s evolution throughout development.
Stay tuned for more updates, and prepare to dive deep—Subnautica 2 is shaping up to be the most immersive entry yet.
