From publisher blurb: Battlelogs: Tanks of the Port Arthur Korps is a supplement for Heavy Gear D6, detailing the combat vehicles that made the Colonial Expeditionary Force so terrifying during the War of the Aliiance. Hovertanks are included from both the original Heavy Gear roleplaying game, the Heavy Gear Tactical Rules and the current Heavy Gear: Blitz! miniatures game. New entries for Auxiliary Systems and Features (both positive and negative) are also include to expand the vehicle options available in Heavy Gear D6.
