Infernal Machines - A Landships! Expansion Game for 1915 - 1933

From Clash of Arms:

"Infernal Machines is the first expansion kit for Clash of Arms' Landships! game. You must own Landships! to play Infernal machines. Designed by Perry Moore, Infernal Machines retells the story of man versus machines in 20 new scenarios. These range from the technological fantasies of the Great War through the gritty Russian Civil War, to the deserts of Morocco and the high altitude Chaco.
With two new double-sided map panels and 280 counters, Infernal machines is fully compatible with Landships! and provides new vehicle and terrain rules to improve the basic game. The infantryman's war is not neglected either. The first mortars, SMGs, body armor, and light machine guns all make their deadly appearance. For artillery (the real killer in action), Infernal Machines explores the ticklish intricacies of single creeping and double creeping barrage lines, interdiction fire, counter battery and suppression fire."
