Set 10,000 years earlier than the canon 40K universe - in an era where civil war turned space marine against space marine - Betrayal at Calth chronicles the battles fought beneath the ruins of the world Calth as Kurtha Sedd and his Word Bearers marines stalk Captain Aethon and his Ultramarines in one of the earliest battles of the galaxy-spanning civil war known as the Horus Heresy.

The all-new Horus Heresy: Betrayal of Calth game is different from other games set in that world.  The game is scenario based, with a “campaign” of six interconnected scenarios included in the box.  Additional scenarios will be published by Games Workshop, with the first appearing in next week’s White Dwarf magazine.  The scenarios are played out on a geomorphic map, composed of four double-sided board tiles, using a dozen custom dice and a deck of 42 game cards.  Tokens and markers are also included.  MSRP is $150.00.

The 38 highly-detailed Citadel miniatures included in the game will be of particular interest to Warhammer 40,000 collectors, as this is the first time that models from the Horus Heresy era have been made available in plastic.  These models will be fully compatible with the Warhammer 40,000 tabletop miniatures game and the entire line of Forgeworld resin models from that era.  Space Marine models are the best selling series in the Games Workshop line, and 40k frequently ranks at the top of the chart for non-collectible miniatures (see “Top 5 Non-Collectible Miniature Lines-Spring 2015”).

Altogether, 30 Legion Tactical marines in “Mark IV” armor, 5 Terminators, 1 Contemptor Dreadnought, 1 marine Captain, and 1 marine Chaplain are included in the set, all without sculpted Legion markings so they can be used with any Space Marine army.

Games Workshop will also offer retailers promotional support for this release with items including banners, incentive copies, and party boxes with giveaway items depending on order size and availability.
