Warmaster is a ruleset for tabletop wargames written by Rick Priestley, published by Specialist Games (a division of Games Workshop), and set in the Warhammer Fantasy setting. It is different from Warhammer Fantasy Battles in both appearance and gameplay. It is intended for 10 –12 mm miniatures. Basic troops are based on stands, of which typically three make a unit. Generals, Heroes and Wizards are mounted individually or with their retinue.
Gameplay focuses on command and control. While magic is used in the game, its effects on the game are limited. The game is designed to focus on the general's ability to command rather than just the armies ability to fight.
In the Warhammer 40,000 universe, Epic fills much the same "large scale battle" role as Warmaster does in Warhammer Fantasy, though the two systems do not share rules.
Warmaster is a Dutch old school death metal band from Gouda. The band's lyrical content deals with World War II.
