Summary
Submarine Overhauls
The Summer Update 2026 introduces comprehensive visual and gameplay reworks for five vanilla submarines: Humpback, Orca 2, Azimuth, Typhon, and Herja. These changes include layout adjustments, such as moving the Orca 2's command room to the center, and technical upgrades like the Herja's new power distributor and the Typhon's new pipe weakpoints.
Quality of Life & Multiplayer
Players can now back up their custom submarine designs to the Steam Cloud directly from the editor. Multiplayer stability has been significantly improved with fixes for monster-related network congestion and a desync exploit. Additionally, the fabrication system has been refined to better handle recipes with multiple material requirements, and defense bot ammo boxes can now be merged.
