I predict the following books in this product line:
• Only War: Core Rule Book and description of a crusade in a new sector: The Hallelujah Sector?
• Only War: GM screen
• This means war: free DLC adventure
• The Old Guard: Famous regiments of the Imperial Guard
• We need more men: How to create your own Guard regiment
• Sing Hallelujah: An in depth view of the Hallelujah Crusade
• The Face of the Enemy: Enemies & opponents of the Hallelujah Crusade
• Heavy Metal: vehicles of the Imperial Guard
• The Omdurman Gambit: A three-part adventure in which a handful of guardsmen must save the sector from a catastrophic fate.
Did I get them all?
