Internal Combustion Engine level 1

[Pure Man55]

How do I build a Internal Combustion Engine level 1?

You will need a University, as it's a research technology.

Build your university, after it is completed, click on it, and then you will see a technology list. You will be able to get the rest from there.

Oh, thanks Lhazer, I already have a university. I'll build it now.

Anytime bud.
