Battlefront.com and Atomicboy Software have released the first trailer from Empires of Steel, a turn-based game of world conquest set in the 20th century. Players command various ground, armored, naval and airforce units against up to 20 human or computer-controlled (Artificial Intelligence) opponents. Empires of Steel uses a simultaneous turn-resolution system, better known in gaming as "We-Go". You can form alliances, capture and trade precious resources, research new technologies, and of course form huge invasion fleets and armies to conquer your opponents. Empires of Steel is due to be available in early 2009.
