From publisher blurb: CO-4E (Core) Complete Mecha Factory and Entertainment Capital of the Galaxy, where leagues of mecha combat teams compete among various factions to become the undisputed champions of this popular interstellar sport. Gladiatorial combat between criminals, between mega-corps at arenas across the planet and to some of the moons and planet across the solar system. This is a complete guide for designing custom Mecha builds from tiny to large (starship) scale, as well as complete rules for custom power armor, though as designed you need to choose one or the other, as the rules are less compatible for those wanting both elements in their game. Additional you will find new starship bay options, new armor, personal equipment, weapons, vehciles and starships to supplant your Mecha combats. Bonus content, both virtual tabletop and print ready maps for included mecha combat zone maps - desert zone, forest zone, junkyard zone, terraform platform zone, and the fore and aft sections of a colossal starship zone.
