The ruleset is based on six-sided and ten-sided dice and uses inches for movement and range measurements. Energy points are renewed every game turn based on the structural integrity and allocated to actions such as: movement, attack, and defense. Structural integrity is tied to the energy point supply, and damaged vehicles find themselves able to do less and less. Critical damage is also possible, leading to an immediate destruction. Another interesting and unique feature of the system is the use of "Battlepoles", these were rods segmented into six 5 inch parts which were used to position the Mechas! at their relative altitudes and added a unique 3D feature to the game. These items could be built by the players or bought from Seventh Street Games as a deluxe set made of clear plastic which greatly enhanced the playing experience. The game was intended to be played with actual model kits ranging from 1/100 to 1/300 in scale, these were not produced by the company but they were intended to be purchased, adapted, built and painted by the players from commercial available kits of series such as Gundam, Macross and other mecha, actually the Canadian magazine "Mecha Press" published various articles where the writers used 1/144 mecha kits and the living room floor as battlefield. In addition to the mecha themselves, the game supports more conventional forces including tanks, fighters and infantry in powered armor. Other features include three-dimensional air and space combat, rules for increasing crew experience, three campaign systems, a mechanical design system and several generic battle scenarios.
Setting
The system was intended to be generic and the rulebook included a number of scenarios which could be adapted to any story. However, the authors also included its own "Azteca Sourcebook and setting" depicting a fictional Aztec Mecha World a universe based on the Aztec Mythology, they turned the Gods into Giant Machines which ruled and fought for the dominance of an alternate Mexican Empire. Later, a sourcebook and several resin miniatures would be released to support this setting.
Expansion Sets
The game received an official expansion, Spirit Warrior Empire, in 1995. The focus of this supplement are the Azteca, a space-faring race whose holdings comprise what is now known as the Spirit Warrior Empire. The book featured more missions, new mecha designs, and the complete history of the Azteca and their portion of known space.
