Mine for ore and discover hidden powers as a steampunk robot!
SteamWorld Dig is a Metroidvania style game with a focus on mining. You play as a robot that has inherited his uncle's mine out in the desert. The local townsfolk are happy to see the mine re-opened and gladly assist you via purchasable upgrades. They also happen to know a thing or two about your uncle, particularly that he's hidden a lot of specialized tech down in his mine.
