You never quite know what you're going to find when you dig a hole. Dig a big enough hole and you might find something truly historic. Such is the case for the robots who were just minding their own business, digging coal out of a quarry. Then, one day, they found something strange a mystical: a coal heart. Not just a funny-looking rock, but this coal heart could grant ultimate power to anyone that held onto it for 24 hours. Naturally, all the robots wanted that power. As such, everyone's fighting over it. That's where you come in as one of the greatest robot fighters ever. Will you manage to hang on, or will you become part of the ever-growing pile of rubble? That's the story behind Robots: Battle for the Coal Heart, up on Kickstarter now.
