The Grand Crusade’s first edition sprang from the Mighty-Empires ruleset that Azyr Empires is based off of. A desire for strategic map-play using a sector-wide set of space that incorporated full Battlefleet Gothic and Warhammer 40,000 rules, the Grand Crusade was born.
The First Edition of the ruleset incorporates Imperial Armor Badab War as its setting.
The Second Edition of the ruleset is much slimmer and does not involve a map element or combined games, and uses just the Warhammer 40,000 8th edition rules.
