AHQ is a revised and expanded version of the GW/MB HeroQuest game. The basic concept is the same: four heroes venture into a dungeon to fight monsters and gain tresure, but AHQ's rules are more detailed and complex.
The major additions and changes include:
- random dungeon generation system
- modular game board
- ranged combat
- multiple colleges of magic and spell books
- henchmen
- critical hits and fumbles
- fate points (the "undo" feature)
GW set AHQ in the Warhammer universe, presumably to foster sales of their miniatures. The campaign world is easy to ignore, however, should players rather keep things generic. AHQ also includes rules for using the characters and monsters from HeroQuest, should players want to do so.
The game is supplied with Skaven figures that make up the quest within the rulebook.
