Burn your enemy out of forests, or hide behind dense walls of smoke. Claim the high ground and crush your foes in the valleys below. High winds blow smoke and deflect arrows, and rain douses flame. Watch the skies; falling aerial units can make an impression on infantry. Close ranks in melee, and scatter your troops as artillery rains down. Hack and slash through armies as a powerful hero. Become a master of arms as you directly control one of four legendary heroes. Master each hero’s special attacks and combos and wreak havoc on your foes. Change the tide of battle. Cut down officers and watch their ranks crumble. Call on allied heroes to assist you in battle, each with their own unique skills & spells. One warrior can’t win the war. Command your troops from the tactical map as you fight. Reforge your soldiers in the fires of war: Watch the campaign unfold across a 3D world map, and lead your troops across it.
