Advanced Dungeons and Dragons BattleSystem is an updated rule set from the original BattleSystem released in 1985. The updated rules are compatible, but do not depend upon AD&D second edition. As in the original version, the system is designed to use D&D miniatures in a tabletop miniatures battle system. The updated version focuses more on dice rolling and simplified statistics in order for players to spend less time on record keeping. The rulebook is divided into three sections each with three sample scenarios. The sections are for basic, intermediate and advanced rules. They system is designed to allow play with any, all or none of the intermediate and advanced rules. The basic section contains the essential rules for the game including miniature statistics, movement, combat and moral. The intermediate section adds special historical units including skirmishers, specialists, heroes and commanders. Expanded movement and combat rules are also included here. The advanced rules add fantasy elements to the game including flying creatures, magic, spells, undead and artillery. Additionally, rules for structures, barriers and fortresses are included. The book also contains a painting guide and rules for converting all of your D&D miniatures into the system.
