Overview | Command-line options | Server commands | Server options | edit navbar The Freeciv server is the core of the Freeciv system. It maintains the complete states of all game variables (map, units, cities, research, etc.), updates them based on player client requests, and sends updates to the clients. For multiplayer games it is the central arbiter of the game's progress. For solitaire play, it implements the Artificial Intelligence (AI) nations. As the game progresses, server commands can be used to adjust game options, save the game for later restart, or terminate the game.
