Oil Tycoon! Big Oil Inc ending
Big Oil Inc is where Oil Tycoon! ends. The building, the confrontation with John Oil and the choice made there feed directly into both endings — this page covers the location itself.

What Big Oil Inc is
- The antagonist corporation on the map — the "oil monopoly" Miguel's shop line tells you to destroy.
- Its building carries a BIG OIL INC. sign and three smoking stacks; one of the official screenshots shows it on fire.
- A destination, not a boss fight: nothing there tests your build, and you cannot fail it.
The confrontation
John Oil is inside, and the scene plays out in dialogue before anything else:
"Turn around slowly. Whoa. Big Oil. Is that you? John Oil."
"Throw this oil. All the other companies would die."
"You can't blow up Big Oil."
Then the choice — one decision, two answers, each with its own badge:
| Choice | Result | Clear rate |
|---|---|---|
| Blow it up | Ending 1 | 18.7% |
| Show mercy | True Ending | 6.3% |
After the choice
The plot returns to normal either way: workers hold the line, the pit refills, and the shop is where you left it. Miguel has a gift waiting either way — droppers run 25% faster in a verified run — and the world stays open: secrets, the mine, fishing and the rebirth door all remain.
What changes is what the game was about. With both badges held, Oil Tycoon! becomes the sandbox underneath the story: balance, expand, chase the remaining badges, or beat your own time trial record.
Why it is called a monopoly
Because your plot has one buyer. Nothing in Oil Tycoon! lets you sell elsewhere — every unit goes through the same channel, which is the story's point and also the mechanic's constraint: your income scales inside a system someone else owns, until the ending lets you decide what happens to the owner.
Before you trigger it
Cash out anything you still want, because the choice ends the run as you know it. If you have not held the six secrets yet, collect them first — badges persist across rebirth, but a fresh run means walking back out to every location on the map.
The two outcomes are documented with their exact conditions on the true ending page and the ending one page, so you can pick deliberately instead of reloading.
FAQ
What is Big Oil Inc in Oil Tycoon!?

What happens after the choice?
Either route ends the story and returns you to your plot; badges from both choices persist, so a replay can collect the other one.
