Subnautica 2 Hits Very Positive on Steam in First 24 Hours

The Steam verdict at T+24 hours

Steam's "Very Positive" verdict requires 80-94% positive across a large enough review pool. Subnautica 2 hit that band inside the first day with a sample size large enough to make the initial verdict meaningful.

For context: an Early Access launch with this much pre-release attention often lands at "Mixed" or "Mostly Positive" on day one because expectations clash with the narrower EA feature set. Hitting Very Positive on day one is the harder outcome.

October 4, 2026 checkpoint

The October 4 Steam review API check returns Very Positive after Buddy System Hotfix 1. The all-language summary contains 116,703 positive reviews, 11,534 negative reviews and 128,237 total reviews, or 91.01% positive. The English-language summary contains 72,700 positive, 5,412 negative and 78,112 total reviews, or 93.07% positive.

Sources and method: the live verdict can be checked on the Steam review page. Counts above come from the all-language API summary and English-language API summary, checked October 4, 2026. Both use all review types and purchase types. Steam's visible store summary can use different filters or change as new reviews arrive.

The wider all-language percentage is lower than the English-only snapshot, but both remain inside the Very Positive band. The useful signal is volume: the review pool is now large enough that the verdict is no longer just a day-one fan wave.

What players are praising

• Underwater visuals. The most common positive theme in the launch-day pool is how good the underwater scenery looks at the EA launch build. Biome variety, lighting, and creature animation get repeat callouts.
• Co-op stability. Mixed-platform sessions (Steam + Xbox + Game Pass) are joining without the matchmaking pain that typically marks Early Access launches. See the world sharing update for the current SaveSync wording.
• "More Subnautica" feel. Reviewers describe the experience as a continuation rather than a reskin. The core loop of dive, scan, build, and progress is intact, but the planet, fauna, and systems are new.
• Scale. The size of the playable area at launch is larger than many reviewers expected from an Early Access build.

What players are flagging

• Content depth versus Subnautica 1 full release. The most common caveat. This is an Early Access fact, not a bug; the launch build is the baseline, not the final scope.
• Onboarding clarity. The Digestive Incompatibility mechanic and the DNA Modification pipeline are not explained well in the first session, which created false-positive bug reports.
• Targeted bugs. The client-side wall demolition bug was the first co-op issue tracked here. Hotfix 3 now covers DLSS 4.5, DLSS crashes, DLSS settings persistence, Frame Generation availability, Interior Wall costs, Hammerhead / Tadpole behavior, Nibbler and Marrowbreach tuning, multiplayer rejoin position, Strike Armor stacking, Tadpole Haul Chassis passenger goggles, and rare startup crashes.

How to read this signal

Three things to keep in mind when reading any 24-hour launch verdict:

1. Launch-day samples reflect early buyers. The October 4 checkpoint covers a larger review pool than T+24h, after Adaptive Measures, Hotfix 4, Experimental, Buddy System and Buddy System Hotfix 1. It remains a summary of posted reviews rather than every player’s opinion.
2. EA reviews carry an asterisk. Steam labels them clearly, and most reviewers grade against EA expectations, not 1.0 expectations. A drop is possible if the patch cadence slows.
3. The volume matters more than the percentage. A Very Positive verdict on 1,000 reviews is fragile. On 10,000+ reviews it's a real signal. Subnautica 2's launch volume puts the verdict in the durable category.

The next review checkpoint

The verdict has now held at Very Positive beyond the first 30 days. The next meaningful checkpoint is a major content update or a directional rating change, not a daily count fluctuation. If it drifts to "Mostly Positive" or "Mixed," the content cadence and bug response speed become the key drivers. The news desk will cover the trend as the data matures.
