Striking black gold and building a massive energy empire from absolute scratch is incredibly satisfying. Oilman drops you right onto an untouched island packed with raw minerals and crude oil, and it is entirely up to you to drain it dry. You aren’t just casually digging in the dirt. You are aggressively grinding to build a highly profitable extraction business, and it actually takes some serious hustle to get your operation off the ground.

DITCH THE BASIC PICKAXE FOR HEAVY MACHINERY

You start your mining journey the hard way swinging a basic pickaxe. It is a total grind at first, but that early effort pays off fast.

Before you know it, you are heavily reinvesting your profits into massive, modernized drilling rigs. The core strategy here is painfully simple: the deeper you aggressively tear into the earth, the bigger the payout. Smashing through those tough geological layers reveals ridiculously huge underground oil tanks. Once you finally drop heavy excavators and industrial suction tubes into the mix, the gameplay beautifully shifts. Your manual tapping slowly turns into a highly efficient, automated operation that pumps serious cash while you basically just sit back and supervise.

EXPAND YOUR EMPIRE AND UNEARTH WEIRD SECRETS

You definitely won’t be stuck on that starter island forever. Once your revenue absolutely explodes from hitting a massive subterranean oil reserve, it is time to pack up and expand.

You take your heavy machinery and start aggressively island-hopping, claiming fresh territory to continuously grow your billionaire empire. Every single new map is loaded with untapped fields desperately waiting to be drained. But it isn’t just about the money. The absolute craziest part of digging this deep is stumbling across what is actually hiding down there. You will randomly punch through a rock layer and uncover totally bizarre, secret underground bases and weird unsolved mysteries completely buried beneath the islands.
