Rochard follows the story of the humble astro-miner John Rochard. John and his mining team accidently discover an ancient structure hidden deep in an asteroid, thus proving mankind isn’t alone in the universe. Soon after, his team goes missing without a trace and John finds himself stranded on the asteroid. To make matters worse, space pirates attack the mine, and John quickly realizes there are surprising and dangerous forces at work, determined to use the mysterious discovery for their own sinister means and eliminate John and his friends along the way. Using only his wits, everyday mining tools and a healthy dose of sarcasm, John must fend off the pirates, save his team and solve the mystery behind his discovery.

The game tests players' coordination and wits as they use gravity to their advantage, changing it at will to solve environmental puzzles and advance through each level. By using the upgradable G-Lifter, the main tool of the game, players can lift and maneuver heavy objects around the environment, and can eventually swing, jump and propel themselves huge distances throughout each level.
