pretty much the title says it all
the basics of the game took place in a post apocalyptic word in which you defend a headquarters and generate power, however you needed to choose the right type or types of power generation to power your defenses, if you for example chose coal then you would have a high smog level (which made zombies harder to kill) or you could choose solar which would give you 100% clean energy but didn’t work when it was cloudy or at night
there were other types of power gen as well like geothermal and ethenol.
would be really nice if anyone knows the name of the game i am talking about
oh and you needed to deal with waste (garbage) so you also needed a way to power your garbage trucks and such
