From the post:
In Scrapyard Empire, the wealthy and eccentric inventor, Sir Winston Derbyshire dies, with no heir to inherit his vast estate, including its expansive scrapyard. In his will, he announces a competition for the inheritance that anyone may enter. The rules are simple: build two of his amazing inventions using parts found in the scrapyard. The first person to build them wins the entire estate, as well as the prestige that is earned in winning the contest.
