The gameplay is "co-petitive" for up to 4 players, meaning that players must cooperate in order to play the game, but that they also compete to collect the most valuable minerals. Jump-in/jump-out multiplayer allows players to join and leave at any time without interrupting gameplay.
Set on Mars in an alternate Cold-War era, Super Motherload is a couch co-op digging adventure with storyline by Image Comics' Kurtis Wiebe, a fully voiced cast of Soviet and American characters, and a procedurally-generated world that changes each time you play. Purchase powerful upgrades and supplies for your mining pod as you progress and prosper, as well as rare special abilities with random availability.
You, the player, work for Solarus Corporation, an interplanetary mining operation that has developed the infrastructure needed to harvest the precious resources of Mars to meet demand back on Earth. Soon after being dropped on Mars, you begin to discover that things aren't quite as they seem.
