Rochard is the story of burly asteroid miner John Goodman Rochard, his accidental discovery of an ancient alien artifact, and his quest to protect it from his nefarious corporate employer. It’s a story of lasers, gravity, physics, and boxes dropped on the heads of badguys.
Rochard begins the game with naught but his G-lifter and somewhat preposterous jumping height for a man of his, uh, build. The G-lifter will snatch items from anywhere on the screen (assuming an unblocked line of sight) and pull them to Rochard, whereupon they can be set down or launched as projectiles for both puzzle and combat applications.
Rochard later acquires the ability to create zones of low gravity and fire a mining laser at enemies, alongside a handful of other offensive and puzzle-based upgrades. In true Metroid-fashion, these upgrades enhance Rochard’s ability to explore and navigate the world, while skipping the backtracking that characterizes that series.
