Hi, a Marathon game brings more fights - more zombies. What are your ideas? I have seen for now that AI and City states cannot stand agains them. So support whovere i want to have in the game by - getting souverign of city states to upgrade theire units, and helping AI by fighting zombies off. All that is difficult on Huge maps, and also i wonder - a destroyed city state does not free up a city state slot for the barbarian tribes.
