Version 12.18.16

📅 2026-10-02 by Guigui

New:

  • New City: the former City and Resources sections make way for a single City, the first section of the game, available from the start — an island of 36 plots to build freely
  • 18 buildings to build and upgrade, each with its own illustration: Housing, Farm, Sawmill, Mine, Market, Barracks, Prison, Clinic, Park, School, Laboratory, Exploration base, Zoo, Power plant, Stadium, Arena, Circuit and Auction hall
  • Settlers: welcome new settlers (one at a time or as many as possible), then assign them to buildings, by hand or automatically
  • Production: Farm, Sawmill, Mine and Market continuously harvest Food, Wood, Materials and Kii; the other buildings raise the city's security, health, education, science, environment, energy and happiness
  • Energy and pollution: past 6 buildings, a Power plant and a Park become necessary to avoid lower production and happiness, flagged in an alerts panel
  • Construction: up to 2 builds or upgrades at the same time, with the remaining time always visible
  • City: special upgrades (build speed, costs, capacity), 10 badges to unlock and a "City life" log

Changes:

  • Renamed sections: Trading Post becomes Market, Technologies becomes Laboratory, Race becomes Circuit, Exploration becomes Exploration base, Penal Colony becomes Prison
  • Market, Laboratory, Zoo, Circuit, Exploration base, Arena, Prison and Auction now require, on top of the XP threshold, their building in the City — the message shown on a locked section states what is missing

  • A welcome message introduces each section on the first visit
  • Reorganized side menu: language choice under the logo, sections to unlock right after the playable ones, scrolling with the page
