Cold Waters

Cold Waters launched on June 5, 2017. At launch, Killerfish Games stated they were "committed to improving the game with future content." True to that, they delivered a significant stream of free updates throughout 2017 and into 2018, culminating in the major South China Sea update on May 16, 2018 — which added an entirely new campaign, new playable submarines, new vessels, crew voices, and numerous gameplay improvements. All of this content was delivered free to base game owners. After the South China Sea update shipped in May 2018, developer communication on Cold Waters effectively ceased. The subsequent news posts (from April 2020 onward) are exclusively about Killerfish Games' next title, War on the Sea, which launched in February 2021. There have been no further updates, announcements, or patches for Cold Waters since May 2018 — now more than eight years ago. The game has only one DLC listed (the soundtrack, released at launch), and no unreleased DLC exists. The developer has moved on to a new title and has not communicated any plans to return to Cold Waters. The game shipped as a complete, fully-updated product with the South China Sea update representing the final major content release.
