SteamWorld Dig is a 2D mining adventure starring Rusty, a steam-powered robot who arrives in the small western town of Tumbleton to take over his uncle's mine. You dig downward through layers of rock, collect ore to sell in town, and spend the money on better tools and new abilities, uncovering what lies far underground as you go.
It is a single-player game that mixes platforming, light combat and puzzles, with metroidvania-style upgrades that open new paths. Its pace is steady and rewarding, and it is fairly short, so it suits players who enjoy a satisfying loop of digging, upgrading and exploring.
