“Comrades no longer need to suck on comically long straws to extract oil from ground. Glorious!”
Oil rigs are the sixth tier in the Ore industry. They cost 1 B Deep Bores, 100 NN Ore, and 3 Comrades. They produce Deep Bores and are produced by Tankers. They are automated by Lt. McRhodey, who is unlocked at Rank 33.
An industry with a similar name and appearance appears in Adventure Capitalist.
