S.O.N.A.R. Release Date: October 29, 2026 on Steam

S.O.N.A.R. - Submarine Operators Not Actually Ready releases on October 29, 2026 on Steam. The date appears in the release field of the official Steam page and was repeated in the developer's Steam announcement titled "S.O.N.A.R. Release Date Announcement" (September 14, 2026). The same page describes the game as not yet available and says it "plans to unlock in approximately 7 days."

The game is developed by Abylight Barcelona and published by Abylight Studios, and it sits in the same universe as the studio's earlier One Military Camp.

What you can already play

You do not have to wait for launch to try it. The Steam page carries a demo download, and the developer's announcements give a clear timeline:

• September 30, 2026 – the playable demo went live on Steam with the single-player tutorial and two selected missions.
• October 19–26, 2026 – a Steam Next Fest demo build added a new 1–4 player co-op mission, plus training stations, progression and customization unlocks. The demo changelog on the store page lists builds such as v0.9.44.0 and v0.9.41.0; those are demo builds and do not indicate the launch version number.
• September 24–28, 2026 – the final public playtest ran, including 4v4 Team Deathmatch and a new co-op mission. The developer's recap says more than 85,000 people played and that the average session was about 1.5 hours. That playtest window has closed; the request-access flow described in Abylight's July 2026 blog post was for those limited test periods.

If you want the game on day one, wishlisting it on the Steam page is what the developer points players to for launch notifications.

Price and edition notes

The developer's "S.O.N.A.R. Price Reveal" announcement (October 5, 2026) states a launch price of $9.99 / €9.39 with regional pricing and an additional 15% launch discount. That is an announced figure rather than a store listing: the Steam page's price field is not filled in ahead of release, so treat the number as the developer's stated plan.

One detail worth knowing before you assemble a crew: the store page's short description says 1–6 players, while the longer description and the release-date announcement both describe 1–4 player online co-op with up to four crew members managing nine stations. For planning purposes, the four-crew framing is the one that matches the gameplay description.

Platform limits

As of 2026-10-22, the official Steam page lists Windows under platforms, with minimum and recommended specs for Windows 10 and Windows 11 (64-bit) and 5 GB of storage. It also lists full controller support, Steam Cloud, Steam Achievements, Steam Leaderboards and Family Sharing. The page's Steam Deck compatibility field reads "Unknown." Because the release is Steam-only in the material here, other storefronts or console versions are simply not described by this page.

An earlier Abylight blog post about the playtest, published 2026-07-21, referred to a full release in 2027. That line is superseded by the September 14 release-date announcement and the store page, both of which say October 29, 2026 — if you see 2027 quoted somewhere, it is from that older post.
