What is S.O.N.A.R. - Submarine Operators Not Actually Ready?

S.O.N.A.R. - Submarine Operators Not Actually Ready is a first-person multiplayer submarine sim from developer Abylight Barcelona and publisher Abylight Studios. The official Steam page lists it for release on October 29, 2026, places it in the Adventure, Casual, Indie and Simulation genres, and highlights Multi-player, Online Co-op, Online PvP and Steam Achievements among its features. The crew shares nine critical stations in first person, and the developer's own description has the sonar operator tracking contacts while everyone else keeps the boat alive.

A free demo went live on Steam on September 30, 2026 with the single-player tutorial and two selected missions, and the Steam Next Fest build announced on October 19, 2026 added a co-op mission for 1-4 players, training stations, controller vibration and a reworked navigation view, logged as demo build v0.9.44.0. That demo is the only playable build while the full game stays unreleased, so this wiki separates what the demo actually contains from what the store listing promises for launch.
