From the publisher:
Land Ironclads is a companion game to Aeronef: Victorian Science Fiction Flyer Combat Rules, the immensely popular rules for aerial warfare in an alternative late C.19th by Wessex Games. As its name implies, LI deals with combat on the ground in the same period. The kings of the battlefield are huge fighting machines, the Ironclads of the title, which cross the landscape on tracks, wheels or even primitive mechanical legs, dealing destruction wherever they go. Small steam-driven machines, known as contraptions and akin to the tanks of the First World War, scurry between the hulking ironclads creating their own smaller form of mayhem. More conventional infantry, cavalry and artillery units, albeit augmented with all manner of fantastic weaponry, add to the confusion. Giant aeronef, dirigibles and winged aircraft fight their own battles in the sky while raining down bombs on the units below.
