Silent Shark
tactical map-based WWII submarine sim. Command a U.S. submarine across the WWII Pacific. Plot contacts, solve TDC attacks, man the deck gun, play with a controller, and add mods from Steam Workshop. I posted an early beta of this game a few months ago: https://news.ycombinator.com/item?id=48180924 - May 2026 (45 comments) and today released the full version.

A lot of it was enabled by the latest AI models like Opus or Astra, I feel like I can finally express myself without being bogged down in asset work or programming.
