This time everything happens underground. What is there?
Explore minerals, craft replacement parts, assemble your Drilla, boost it and do the upgrades.
Be a geologist, a chemist, an engineer, a constructor and a simple handy miner in at a single time. You’ll see that is easy.
Gnomes! Gnomes will help you everywhere. Sometimes evil Egor will come to your mine. This guy is bad. You better kick him off.
