Abylight Barcelona and Abylight Studios announced S.O.N.A.R. - Submarine Crew, Not Ready! (also called Submarine Crew, Underprepared!) in July 2026. The game is a cooperative submarine simulation for one to four players. Players manage nine stations including navigation, sonar, and damage control, while also tracking food, health, and rest. Missions include combat, stealth, escort, and treasure hunting. The game emphasizes chaotic teamwork where a single mistake can sink the submarine.

The developers are working with cooperation from the Spanish Navy. The game features proximity voice chat and character customization. Playtest signups opened on Steam shortly after the announcement. The full release is planned for Q1 2027. Other platforms are undecided.

The coverage frames the game as part of a trend where cooperative games turn failure into entertainment. The stories consistently describe the same core mechanics and release window, with minor title variation between the announcement and later coverage.
