n an alternate past, steel, steam, and oil have become essential resources for the military forces of the age: gigantic steel colossi weighing several tons, steered by half a dozen men and women. These machines maintain the balance of power between the four largest empires. But machines require fuel - which is a scarce commodity. In tactical battles against rival teams, players get to showcase their strategic skills. A vehicle on high ground, for instance, will have increased firing power and range. On the other hand, craters and canyons offer better protection against attacking enemies. Other elements that provide players with tactical options during missions include bridges, barriers, turrets, and various buildings. In addition, by replacing individual components of Steel Legions combat vehicles, such as chassis, drive mechanism, and armour, as well as primary and secondary weapons, players get to customise their vehicles and influence their combat attributes.
