Iron Heart

Iron Heart is a tower defense game set in a Victorian-era steampunk world. Hordes of invaders emerge from beneath the earth to enslave the surface's people, and you lead the planet's defenders in their resistance against an army of steam-powered robots.

Defend the depths

You place towers in tactical positions to protect your base and use special skills against the enemy. Across 40 levels of varying difficulty, you venture through icy mines and an abandoned underground city, descending further into the planet to search for the source of the threat. You must also defend your machines from enemies with different traits: some are armored, some fly, and others are vulnerable only to electricity.

Towers and enemies

The game includes 12 types of towers and skills. You earn rewards and upgrade your weaponry, then use enemy weaknesses to your advantage. Enemies have more than 15 special characteristics.
