Hostile Seas

Command the Counter-War

Free · Designed for iPad. Not verified for macOS.

Free to play — no ads, no IAP. Build your fortress, design your fleet, and out-think rival Commanders in one persistent shared world. Command begins now. Hostile Seas is a persistent-world naval war strategy game where Commanders build island fortresses, design warships, and lead combined sea, air, and land forces into real-time 3D tactical battles. There is no overpowered fleet here — only doctrine. Every weapon system has a hard counter: aircraft fall to anti-air, missiles die to interceptors, submarines are hunted by sonar. Copy-paste fleets lose. Commanders who think in counters win. Build your fortress. Raise turrets, expand tiles, grow your economy, and fortify your island against raiders and the AI Directorate that never sleeps. Design your fleet. Enter the warship refit yard and configure weapon mounts, armor belts, and sensor suites. Study doctrine report cards to expose enemy weaknesses before you ever fire a shot. Command combined arms. Naval fleets, aircraft squadrons, and land battlegroups move together in real-time 3D battles where positioning and counters decide the outcome, not brute force. Rise through the ranks. Train at the War College, test new doctrines in the Proving Grounds, then take your fleet into a single persistent shared world to raid Directorate strongholds and rival Commander bases. Forge alliances. Coordinate through live chat channels, sign treaties, and climb the world rankings alongside — or against — thousands of other Commanders. One command record, every device. Your research tree, blueprints, campaign progress, and achievements follow you wherever you deploy. Hostile Seas is free to play — no ads, no in-app purchases, just the fleet you build and the doctrine you master. An online connection is required to join the shared persistent world. The sea rewards the Commander who thinks. Deploy now and prove your doctrine.
