Place gears. Merge weapons. Crush zombies.
Gear Defense is a merge tower defense game where gears power your weapons. Drop gears onto the grid, connect them to activate turrets, and merge matching gears to evolve your arsenal into devastating firepower. Miniguns, flamethrowers, rocket launchers, snipers, shockwave blasters — all driven by spinning gears.
⚙️ GEAR-POWERED WEAPONS
No ordinary tower defense. Your turrets only activate when gears connect. Build gear chains, optimize your grid layout, and rearrange between waves to maximize damage output. Every gear placement matters.

Zombie hordes, mutant rushes, and boss attacks hit harder every round. Merge your gears fast enough or get overrun.
