Citizens: Prologue is a turn-based hybrid of a city builder and strategic puzzler where you create beautiful cities, manage resources, plan long term investments, trade with foreign civilisations and look after your subjects. Explore beautiful islands, deal with difficult problems, and think about your next move very carefully, for it could be your undoing!




Prologue offers:

• New approach to city-building games
  
• Seven scenarios introducing you to basics of the game

Additionally, the full game offers:

• Three campaigns with challenging quests and varying difficulty levels
  
• Over 50 buildings spread over numerous production chains
  
• Over 30 different resources to extract, process and manufacture
  
• Mechanics to spice up your experience such as plagues, fires and winters
  
• Combat and Trade
  
• Endless fun with random level generation

Meet various civilisations along the way. Sightsee ancient temples, trade with scattered outposts, and defend yourself from plunderous Vikings! Be mindful... Ravaging barbarians are not your only enemies. Fire and Plague can be dangerous too.
