Gears against
sky pirates

Sky pirates raid your floating harbor in waves. Build a gear train from the motor to your cannons, gatlings and harpoons, then keep it turning while they try to shoot it apart.

Cogwind mid-wave: a gear train drives two cannons, a gatling and a repair crane while pirate gunboats attack

The drive train

Every gear
is a decision

A weapon only fires while a turning gear drives it. How you build the train decides how your harbor fights.

1

Speed sets the fire rate

The faster a weapon's gear turns, the faster it fires. Every mesh changes the speed, so a small gear driven by a big one spins up.

2

Size trades speed for punch

Big gears turn slowly but hit hard. Small gears fire often with lighter shots. Medium sits in between.

3

Direction picks the ammo

Each mesh flips the spin, and clockwise or counterclockwise decides what a weapon loads. Close a loop that forces a gear both ways and the whole train jams.

Features

Build. Defend.
Repair.

Build, then fight

Every wave starts with a build phase. Place gears and switch weapons, then tap Fight for half a minute of real-time combat.

Gears break

Pirates shoot your gears mid-fight and the train stops. Tap to repair with scrap, drop in a replacement or let a crane mend it.

Merge up to tier 4

Drop a gear on an identical one to merge it up a tier: more punch and more HP, at the same size.

Pick 1 of 3 upgrades

After every wave, choose one upgrade for the run, from twin shot and overdrive to hardened teeth.

A boss every 5th wave

A pirate dreadnought and its chief. Shoot out the two engines, then crack the armored hull.

12 raids, then storms

Fly the sky map through 12 raids. After that, storm raids bring them back with tougher pirates.

Grow your harbor

Harbor buildings unlock the harpoon, shield and repair crane, and swap the crank motor for a steam engine or electric dynamo.

Daily calendar

A seven-day reward calendar to come back to, and a captain card that tracks your raids.
