Roadmap and 1.0 Release

1:13 Subnautica 2 has no 1.0 release date: Unknown Worlds expects Early Access to take "about 2 to 3 years" from its start on May 14, 2026 (Steam, read Nov 4, 2026), which points to roughly 2028 or 2029, and the price will rise when it leaves Early Access. The roadmap of May 15, 2026 set out three steps: a quality-of-life update, a co-op update, then a "next big drop". The first two shipped as Adaptive Measures (Jul 8, 2026) and Buddy System (Aug 19, 2026); the big drop, Early Access 2, is due in December 2026.

Quick facts

The May 15, 2026 roadmap

A day after launch, Unknown Worlds said its updates would "vary from focused improvements that address systems and smaller features, to hot fixes when needed, and then our larger expansions" (Unknown Worlds, May 15, 2026). It named three steps:

1. A first update of quality-of-life fixes.
2. A second update with "requested improvements and additions" for co-op.
3. The "next big drop that expands on the world, biomes, creatures, resources, tools, vehicles, and brings you the next chapter of the story", with several improvement updates before it.

0:51 The roadmap graphic, as PCGamesN summarized it, listed more passive Biomod slots, docking and fabrication fixes, voice log priority, a storage cache and sprinting in bases for the first update, and proximity voice chat, emotes, revives and customization for the second (PCGamesN, updated May 20, 2026). On Jun 4, 2026 the studio said it would stop "frequent, rapid hotfixes" to focus on 1.1 (Unknown Worlds).

What shipped and when

Each is covered on Updates and Patch Notes, Launch Hotfixes, Adaptive Measures Update and Buddy System Update.

0:22 The plan held, with one change: in June 2026 PCGamesN expected the new region and a "stompy" chassis in 1.1, but 1.1 came without them and Unknown Worlds now ties both to Early Access 2 (PCGamesN, Jun 4, 2026; Unknown Worlds, Nov 3, 2026).

When will Subnautica 2 leave Early Access?

12:14 Unknown Worlds gives only a range: "Based on previous Early Access games we have developed, we expect it to take about 2 to 3 years" (Steam). Counted from May 14, 2026, that is about mid-2028 to mid-2029. That is a reading of the range, not a date, and no 1.0 year has been announced as of Nov 4, 2026. Gameranx's May 14, 2026 Before You Buy read the same estimate as "at least 2 or 3 years" and was content to "let them cook". Steam adds that the full version aims to be "more polished, feature rich", with more content, and the story's conclusion is held for 1.0 (TheGamer, May 1, 2026).

How long did the first two games spend in Early Access?

The studio's own history is the basis for its estimate. By Unknown Worlds' timeline:

Consoles followed the first game's 1.0 (Xbox and PS4 in 2018), which is history, not a promise for Subnautica 2 (Platforms and Cross-Play, Subnautica Games in Order).

The price after Early Access

2:59 "Yes, the price of Subnautica 2 will increase after Early Access," says Steam's Early Access section. It is $29.99 during Early Access, and anyone who buys now gets 1.0 at no extra cost (Unknown Worlds, May 9, 2026). Before Early Access, in its Jun 3, 2025 Q&A, the studio had already said the Early Access price "will be lower than it will be at full release". The 1.0 price is not announced (Price and Editions).
