About World Empires
World Empires is a free turn-based strategy game on a hex map. You start in 4000 BC with a settler, a warrior and a scout on an unexplored, procedurally generated world of continents, rivers, forests, hills and mountains. Found cities, improve the land with farms, mines and pastures, research 49 technologies across six eras, adopt social policies, keep your people happy, and raise armies from warriors up to cannons, cavalry and tanks. Up to nine rival civilizations explore, expand, build wonders, trade, declare war and besiege your cities, while barbarian camps raid your borders. A run ends when someone wins by domination, science, culture, or score at turn 300.
Controls are mouse and keyboard or touch: drag or WASD to pan, scroll or pinch to zoom, click a unit then a highlighted tile to move or a red-outlined tile to attack, click a city to manage production, and press Enter to cycle units and end the turn. Hover or tap any tile for yields and combat previews. Every game uses a new seed, map size, civilization and difficulty, so the world and your neighbors change each time. New players should keep the first-game guide ticked: it shows each move with one button. Progress autosaves every turn.
