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.

This is version 1.03.06 of the game, it is much more stable and has a lot of bugfixes compared to 1.3.1. Released by 3DM so there are some chinese files but the game itself is in english.
Torrent was dead so I found the original files again and I'm re-uploading it.
Please seed as long as possible to avoid it dying again.

If you get the "Steam client is not found" error do as follows (thanks to nickthenack99 and Shakeo64):
On windows, click START, then click RUN, type regedit in the OPEN box and click OK.
In left hand panel open "HKEY_CURRENT_USER" folder, then open "Software" folder and right click on folder, click on New-->Key (to add the first folder then rename to "Valve"), Right click this folder and repeat last step but rename the second new folder to "Steam"
