Naval Fortress Defense

Defend your base. Sink the enemy fortress. A side-scrolling naval strategy game set on a moonlit sea. Tap a card to launch a ship. Read the matchups across three battlefields — surface, underwater and air — and send in the right fleet. ■ 20 UNITS From assault RHIBs to battleships, attack submarines, ballistic missile subs (SSBN), attack helicopters, bombers and drones. Clear stages to unlock new units. ■ MATCHUPS MATTER Autocannon, AP shells, torpedoes, missiles — damage depends on weapon type versus armor. Hunt hidden submarines with sonar. Meet incoming bombers with anti-air fire. ■ BUILD YOUR FORTRESS Mount CIWS, a fortress gun, SAM sites, an EMP tower and a supply dock, and upgrade them to Lv3. Use fortress commands — boost income, expand your vault, repair and fortify — to balance attack and defense. ■ CONTENT - 10 stages plus an endless mode - Earn up to 3 stars on every stage - A codex with every unit's stats and a full damage table ■ PLAY WITH PEACE OF MIND - Completely free: no ads, no in-app p
