The underworld is filled with precious diamonds of various kind and it is your job as an explorer to collect these resources. Equipped with large quantities of oxygen cylinders you must use your shovel to dig your way through the hard underground.

While searching for diamonds you have to be aware of falling rocks and boulders which could potentially kill you. In order to survive you must also keep a close eye on the dangerous creatures of the underworld. Points are awarded for collecting diamonds and for completing levels.
