## What is 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
