The struggle against the army of soulless steel! Prove your courage in a storm of fire and steam! The hordes of the invaders appear from the intestines of the earth to enslave the people of the surface. An iron heart is a strategic game that rotates around the protection of your base, placing tricks in tactically profitable positions and using special skills. The intrigue follows the resistance of the planet’s defenders against the army of steam robots in the rare atmosphere of the Steampank of the Victorian era with stories, mechanisms, mines and underground cities of Jules Verne.
Each level leads you further into the depths of the planet in search of the source of the inevitable threat to the world on the planet. Your task is to protect your car from various enemies - some are protected by armor, some flies, while others are vulnerable only for electricity. Use tactics to use the weaknesses of your enemies and get victory! You get a reward for victories in the form of Cogs, which you can exchange to update your guns, machine guns, transmitters and skills. The battles are held in ice mines and on the streets of an abandoned underground city. Stop the underground threat!
