Constructing a zombie-proof city is the name of the game in They Are Billions, and having the right resources is crucial to be able to survive. Oil is one of best resources that you can have in the game, as it allows you to power the late-game units and upgrade certain buildings to their max level. This guide will show you how to acquire and use oil.
You’ll come across random pools of oil throughout your game time, but once you’ve unlocked the foundry building late in the game and built it, your ability to get oil skyrockets. Having this building will allow you to research refineries, and if you build an oil refinery on a pool you will get 10 oil every 8 in-game hours.
Some advanced units will also require oil to be acquired, which can be researched through the foundry. They will take up a small portion of your production to keep them running, however, so that’s something that you’ll need to keep an eye on. You just want to make sure that your oil refineries remain up and running so that you have a steady stream of oil coming to you at all times.
While you’ll find that oil wont necessarily be a huge help to you early on in They Are Billions, it’s nevertheless an important resource that you’ll want stock up on as you get deeper into the game. You’re going to need the best defenses in order to stave off the zombies, and oil will play a big part in that when all is said and done.
