Here's a Lego Worker Mech from the recently released strategy game Civilization: Beyond Earth. Based on a useful in-game unit, it was designed and built by Firaxis' artist Andrew Clark, just for the team. Now it's been submitted to Lego Ideas for public voting as a potential product.
"I got to design this kit as a present for the studio," said Clark. "The set includes the Worker Mech, one complete minifigure with an optional female head, a Firaxis Sticker for the Bucket, and printed instructions. Total part count 187. A big shout-out to all the folks at Firaxis who kept the secret and helped collate the parts correctly in each set."
