Fight a soulless steel army! Prove your mettle in a storm of fire and steam!

Hordes of invaders are emerging from the bowels of the earth to enslave the people of the surface. Iron Heart is a strategy game which revolves around defending your base by placing towers in tactically advantageous positions and using special skills. The plot follows the resistance of the planet's defenders against an army of steam-powered robots in a rare Victorian-era Steampunk atmosphere, complete with Jules Verne stories, mechanisms, underground mines and cities.

Each level takes you further into the depths of the planet in search of the source of the looming threat to peace on the planet. Your task is to defend your machine from various enemies – some are protected by armor, some fly, and others are vulnerable to electricity. Use tactics to exploit your enemies' weaknesses and achieve victory! You receive rewards for victories in the form of cogs, which you can trade in to upgrade your cannons, machine guns, emitters and skills.

The battles take place in icy mines and on the streets of an abandoned underground city. Stop the underground threat!

- 12 types of mechanical opponents vs 12 types of towers and skills
- Diverse tactical options

The game is great but

The game is great but there's one thing that bothered me a lot about it in the shop you can buy anything you want with your nuts have to buy specifics that you allow and why is that. (Knowing I have the nuts for it)

Solid TD Game

Very good, a few suggestions:

1) Give us some indication of what path the next wave is going to be taking. 2) Make the pause and play button the same button, there's no need for them to be separate buttons. 3) The active zones around each button need to be either bigger or more sensitive, it is quite often a button press does not register.

Hey everyone, this game is entertaining and strategic in that we don't know what enemy is next or do we know from what direction. The only challenge here is swapping out weapons once you see where the next wave starts. I am disappointed I spent money on this TD game.
