STORM OF STEEL (SoS) is a complete simulation of World War I. Three maps cover Europe from the Pyrenees to the Urals along with the Middle East. Fighting rages from St. Petersburg to Verdun to Baghdad and beyond. The maps can be combined for one grand campaign game, or they can be used separately for theater-level campaigns of the Eastern front, Western front and Middle East fronts. Nearly two dozen scenarios allow players to focus on one year and one front, one year on all fronts, start a campaign game from the beginning of any year, play the Eastern front for the entire war, play an alternative history 1919 scenario, or play a Grand Campaign of the entire war. Turns are quarterly, with all units able to move and fight in at least one impulse per turn. Campaign Cards simulate the designation of objectives and logistical preparations, and provide additional impulses and potential combat bonuses to recreate the intense offensives of the war.
