Battle Fleet World is a free browser-based naval strategy game where you command a warship in a single persistent ocean that never resets. Released in May 2026 by MythicalCity and built on HTML5 with Unity WebGL, it loads instantly in desktop browsers with no download required.

You start in a Destroyer, hunt rival players and threats for Scrap, and bank your loot at port before risking it all again at sea. Battle Fleet World is a browser-based naval combat and survival game in which players pilot a single warship across a shared, always-on ocean.

The genre blends action shooter feel with tactical fleet-strategy elements, and the headline hook is permanence: leave port, and what happens at sea sticks.

The game is published on CrazyGames by developer MythicalCity, runs on HTML5 with a Unity WebGL build, and is currently listed as desktop-only browser play. It is free to play and requires no account or installation to start a session.

Matches as such do not exist — instead, every player shares one persistent world with organic encounters, salvage hunting, and a Scrap-based economy. Expect short bursts of intense ship-to-ship combat punctuated by quieter sailing, scouting, and dockside management.

Pro Tip: "Treat every voyage like a roguelike run — bank Scrap at port often, because a single sinking erases everything in your cargo hold and equipment slots." Open-world naval action with light strategy systems, set on a stylized 3D sea with ports, scrap fields, and hostile…

Browser only, currently desktop-focused. Mobile support is not advertised on the official CrazyGames listing.

To play Battle Fleet World, open the game page in a desktop browser, wait for the Unity WebGL build to load, spawn into the persistent world in your starting Destroyer, then sail out, engage threats with your turrets, collect Scrap, and dock at a port to bank rewards.

There are no lobbies and no match timers. Once loaded, the core loop is straightforward but unforgiving. Throttle up with W, steer with A and D, aim turrets with the mouse, and fire on enemy ships or floating salvage containers.

Wreckage and crates drop Scrap, which you sail over to collect. Carry too much, and a single defeat erases it all. Slow down inside the port zone and press E to dock — the port menu opens stores, repair, ammo refill, item equipping, and permanent upgrades.
