I know oil wells come with the standard oil jacks that pump up 1200 units (barrels per hour???)
I know these standard oil jacks CAN be upgraded somehow to pump up 2400 units.
What I don't know is how to obtain the upgraded jacks..........
The story:
I joined a random game once on my server. Already some mega cities were up and running, so I hitched a ride on a lot of regional upgrades as I started.
When I placed an oil well, I tried to place more oil jacks. That's when I was actually able to expand with oil jacks that pump up 2400!!!
So with the courtesy of a neighboring city that had some kind of upgrade.......................but I never figured out what it was.
Ever since I've tried every combination possible to obtain it myself, but so far I have no clue as to how. :-(
Is it an add-on to your City Hall? University or other educational thingie? One of the many specialized incorporation towers?
I've searched the internet for an answer.
I ran across lots of references to the standard wikipedias that just covers the building as it is. Not the upgrades.
I haven't found any kind of tech tree either. Like what building unlocks what other building perhaps.
And youtube is flooded with clips, but all I encounter there are dozens of corny vidblogs of people who think they can explain the game, but all you get is 10 to 15 minutes of "eeeeehhh..........well............uhhhhhm...... " per clip.
Does anyone know what I'm talking about and can anyone help me on this?
