Mine, build, and upgrade your way to freedom...Again! You've, once again, been kidnapped by the evil Mars Corp. and forced to mine for pieces of an ancient artifact buried deep below the surface of six different planets. Finding all of the pieces of the artifact is your ticket back to Earth. You will find many valuable gems and ores along the way that can be sold at the shop to buy more supplies and better equipment to allow you to mine deeper. Make sure you have enough supplies to get back out of the mine! Every mine is randomly generated. No game is ever the same! Music: www.bensound.com
