Each weapon had an attack rating and range. Shields added to defense. Factoid cards could do a wide variety of things, such as freezing an opponent in its tracks or calling in reinforcements. Actions were resolved by rolling a ten sided die. The bioborg could also travel with three different types of support units: infantry, gammajets, and hovertanks. These units had their own movement rules and aided the bioborg in combat. The "Revenge of the Factoids" expansion added three new types of support units: veterans (double-strength infantry), transports (for carrying infantry), and thundertubes (artillery pieces).
