Alongside this exciting new Expansion for Warhammer 40,000 we're releasing a swathe of fantastic new Citadel miniatures to support many of the races, including a new Basilisk and Chimera. In March's White Dwarf we'll reveal all, showing the exciting new releases, as well as introducing the Warhammer 40,000 Battle Missions book itself.
