XGen Studio's follow-up to Flash game Motherload has excavated its way onto Steam Early Access, bringing with it the chance to group up with your friends as you venture into the depths of Mars. Like its console brethren, the Steam version will also offer local co-op, but also includes controller support for four simultaneous players.

Set on Mars in an alternate Cold-War era, Super Motherload is a 1 to 4-player 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 Specials Abilities with random availability.

You, the player, work for Solarus Corporation, an inter-planetary 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.

To help celebrate the release, XGen has the Steam version available at a 10% discount until March 5th, putting it at $13.49. Meanwhile, PlayStation versions are also receiving a hefty discount for the cross-buy title, with price tags of $7.50 until March 3, or $3.75 for PS Plus subscribers.
