Enjoy!

Thank you. I hope that this will help other people. Well time to go get Industrialist now - on asian islands inspired by you :D

Great analysis @Alys1711, i'm sure many other will be helped by your findings. And welcome to the EPEC group!

So to get EPEC you have to supply each city above 10% and do not let it drop to 0% on whole peroid (if you drop "counter" restarts. It should be possible (i got achiev on my map before yours :/) to get on someone save file. Important thing - save should be without mods.

It needs like 4-5 deliveries and not dropping to 0%. Also it's not counted by game'ish time but something connected with stable deliveries. It can take years if you play on 1/4x or months 1/2x.

But i found out that if city is like: 8/100 so 8% (game displays only 10/20 etc) its rounded up to 10% but epec isnt achieved. You need to look at details and supply city above 10% or very close to it so 9-11/100.

So E.P.E.C. isn't so easy to achieve not only from network standpoint.
Also: the longer you play the map, the bigger cities and epec is harder :P

Thanks for answer, i will check that on my own save and then on yours so we can all know

@Alyss1711 It took a month or two to trigger for me. Each town need to get a few deliveries during the same period of time I believe and not drop to 0%. The achievement is not instantaneous. I don't know if you can get the achievement from a workshop download though, but your own save should trigger.

Good work on this map btw :D

Does it work? I am not getting E.P.E.C achiev :/ Neither do i on my save where i have every town supplied by 10-60% on big map
