Newest update: Fleet Battle vs AI (2026-10-09)
- Clearer harbour menu: Fleet Battle vs Player, Fleet Battle vs AI (easy / normal / hard), and Training Bay at the bottom.
- Your selected ship's engine plays close and loud, and the fleet, enemies, guns and splashes carry much farther.
- Captains focusing a target now spread their shots bow to stern instead of all hitting her middle.

@makeriffic · loved it · 2026-10-09 · played 23 min: “I love this game! This is so awesome. I love to control the carrier as the carrier have so many armaments and so tanky. Submarine in the other hand is a sneaky little ninja. Nice graphics too!!”
@lego · needs work · 2026-10-08 · played 11 min: “I’d like to see some bots added! I couldn’t really play it without anyone else in the lobby, but it looks pretty interesting and I’d definitely give it another try with bots”
