One more run. Always.

Easy to learn in ten seconds. Brutally hard to master. Built for "just one more try" – from the first wave to the final boss.

Twitchy arcade combat

Drag to steer, hold to fire. Your deck gun overheats if you spray and pray, so every burst counts.

Combo multiplier

Chain kills without taking a hit to push your score multiplier to ×5. One mistake resets it.

Repair under fire

Shot-down drones drop parachute repair crates. Drive over them to patch your hull – if you can survive long enough.

Boss battles

Every 5th wave, a giant arrives. Iron Tide, Hive Mother, Leviathan, Storm Wing and The Admiral – each with three brutal phases.

Day, dusk, night & storm

Every wave rolls the weather and time of day – from sunny patrols to lightning-lit storm fronts.

Worldwide leaderboard

Post your score to the live World Top 20 – no account needed. The iPhone app also posts to Apple Game Center so you can take on players everywhere.

Know your enemy

Scout drones, bombers, kamikazes, strafing jets, ramming speedboats and warships that fight back. New threats arrive every few waves.

USV Attack enemy roster: drones, jets, gunboats, frigates and cruisers

Five bosses. Zero mercy.

Each boss fight escalates in three phases – missile barrages, bomb carpets, drone swarms and more.

USV Attack bosses: Iron Tide, Hive Mother, Leviathan, Storm Wing and The Admiral

How to play

Drag to steer. Slide your thumb anywhere to swing your USV left and right across the water.
Hold FIRE. Watch the heat ring around the button – overheat and you're a sitting duck.
Survive the wave. Dodge bombs, shells and missiles. Grab repair crates. Take down the boss.
