Pirate fleets are sailing in from every side. Only your tower stands between them and the beach.
ONE THUMB IS ALL IT TAKES
Drag the joystick to aim and your tower fires on its own. Lead your shots, chain sinks into combos and stop every ship before it lands.
24 BOSS CAPTAINS
Every fifth wave, a flagship arrives with a captain on deck and a trick of their own: Old Mother Rime's ice armor, Madame Fizz's firework shells, Lantern Lou's fog, Captain Nobody's decoys and many more. Learn each mechanic, sink the flagship and capture its flag for your Flag Locker.
120 WAVES ACROSS SIX SEAS
Sail from Home Waters through Frostbite Reach, the Ember Archipelago, Hollow Fog and the Thunderhead Expanse to the Abyssal Crown. Each sea brings its own weather and a new kind of ship: icebreakers, fire rafts, phantom sloops, kite gliders and abyss ironclads.
BUILD YOUR TOWER
Unlock the Arrow, Gun and Rocket and level each up to 20 with Weapon Mastery. Upgrade reload and fortress, pick a specialization path and find the build that fits your play.
THREE STARS, THREE DIFFICULTIES
Win, take no damage and reach a combo to earn every star. Easy, Medium and Hard each keep their own record.
MAKE IT YOURS
Restyle your island and ocean with cosmetic skins, including limited seasonal sets.
PLAYS ANYWHERE
Island Defense plays offline and saves on your device. There are no real-money purchases. Optional ads can give you bonus coins, and you never have to watch one.
Defend your island from pirate fleets, sink 24 boss captains and sail six seas.
