Defiance: Vital Ground

From the publisher:

Welcome to the Defiance Universal Skirmish System™, the game of near future and science fiction tactical combat that lets you modify or even create the strategic setting in which your battles will take place. With force sizes varying from one unit to several platoons, each trooper matters, and the correct combination of mobility, firepower, command and control is crucial to your success.

The U.S.S. Army Customizer is a comprehensive and statistically based force construction tool that literally allows you to design any weapon, any trooper and any army that you can imagine, all the while being assured that your creation will be balanced for play against any other U.S.S. force list. A lot of work and testing went into the Customizer, and we feel that you will not find a more versatile or more balanced universal force construction tool on the market today.

The 128-page rulebook contains the necessary rules and army lists to allow players to take part in the battles for the Milky Way. Control the ground forces of one of 5 different empires, all jockeying for supremacy in the new power vacuum that the Starslayers have created:

The Vobian Empire, vast and ancient, which utilizes high-tech weaponry and cybernetic beasts to even the odds against its former subjects.

The Tamerlane Khanate, progeny of the last great Mongol Empire, which still clings to a tribal past, despite the urgings of its human neighbors.
