Build the biggest, most blisteringly powerful battleship fleet imaginable, then fight back against the tyrannical Blackwater navy in this hard-hitting action-RPG from the makers of Bloons TD 5.

Choose one of 3 ship classes, fill multiple gun slots with powerful weapons, and add Modules to get new abilities. Take your custom ship build into one of 15 missions, and unleash pure havoc as you target your weapons, ram enemies to bits, and trigger ocean boiling special abilities. Earn resources and precious Blueprints with each victory, upgrade your ship, and build a fleet of up to 15 ships to wrest command of the seas away from your relentless enemy.

Forget about slow ship simulations you've seen before - this is smooth, one-touch driving with the ability to dodge incoming fire, auto-target enemies, and line up nitro boosts for awesome ram combos.

Blackwater isn't going down without a fight - you'll face dozens of vicious enemies who can form a variety of deadly attack groups. Navigate past enemy turrets and fortifications to crush enemy-spawning factories. Then face off against huge armored boss ships that use every ounce of their firepower and their signature special attacks to send you to a watery grave.

15 different ship types, 16 Bridges, 100+ weapons, and 75+ modules allow you to craft an incredible array of powerful ships. Use Fleet Squadron to call in two of your other ships to tackle tough objectives, or send other ships off on timed missions to come back with critical resources to help you grow even stronger.

In 2063, vast ice shelves in western Antarctica broke free, crushing coastal cities beneath cataclysmic waves, overwhelming nuclear failsafes, and plunging the world into disease, mutation, economic collapse, and regional conflict. Governments crumbled, and in 2065, Aiden Black, head of the world's largest naval military contractor, Blackwater Enterprises, unleashed his stockpiled fleets and seized control of the seas.

You are a captain in the New Coastal Alliance, a coalition of surviving national and private fleets held together by the need to confront Blackwater. You must arm your ship, collect valuable Blueprints to build your strength, and assemble a fleet of warships mighty enough to challenge Blackwater and allow our world to rebuild.

Editors’ Notes

Forget the wooden ships and creaky cannons of a bygone age—the high-tech vessels of Fortress: Destroyer are nimble and lethal. With its instantly accessible one-touch controls, the game offers delightful tactical depth and frantic, explosive action. Guide warships into battle against enemy fleets, fortresses, and monstrous mechanized leviathans while customizing your flotilla with new weapons and upgrades. It’s a couch admiral’s dream come true.

Good game but...

Well let's just get started with the graphics, the viper explosion is just 16 bit BS. To play new levels you have to grind the same ones like crazy. First lvl 1 second lvl 3 third lvl 6 fourth lvl 14 and so on. This can get quite boring if you don't like repeating missions. Secondly, you also have to grind credits and aluminum and that takes quite a while. Also it just feels like to get new ships and better guns you have to pay some money as most of them can be expensive. Finally the blueprints... Really? By selling a blueprint you only get 10%? This game should be 0.99 instead

Decent idea but very limited

Game has a great foundation, especially if you like naval warfare. Build up a fleet of ships you get to customize with various hulls, a plethora of weapons and components as well as with modules and skill points you get as you level up. You can also send ships on missions to earn resources while you don't pilot themselves.

Sadly they put a lot of effort into the foundation but apparently very little into gameplay. Piloting your ship and taking out ships/bases/aircraft is fun the first dozen times. But then you realize you gotta grind the same noob levels 100 more times to buy that next hull, or 1000 more times to level up enough to unlock another level you can grind some more on. They did add random boss encounters and "elite" versions of same levels you can play thru but rewards are still pretty pitiful.

All in all with more things to do it'd be great, but the content isn't there now and if you do spend money to buy better stuff fast you quickly find its pointless because you still don't have anything to do with it
