What is the building time for C20 and above
Hello!
Unfortunately, there is no publicly available information about construction times, without boosts. Therefore, we record these times using one in-game city that has 0% “Building Speed Bonus” (No Officers, nothing developed in the Academy and no Alliance). But it takes a time 🙂
Sooner or later we will have building times for c20+.
Thanks for the question!
You have a type-o on lv26 steel requirement.
Fixed, thanks 😉
What does the two level requirements mean when you can’t upgrade something
Ex:
Main Hall Lvl 8 / Lvl 10
Hello!
This means that you want to upgrade a building that can only be upgraded if the Main Hall is Level 10, however in this case your Main Hall is only Level 8.
In my account there is no mercenary survivor but in its available how get that account n my account?
Hello!
Unfortunately, this is not possible. Only those Cities that are created after the introduction of this mini-game can play this game.
You can read more about the Mercenary Survivor mini-game here:
