Customizing your forces was always my favorite part of the hobby. When I played 40k, I never liked just using models as they came. I loved upgrades. So go check these new kits out.
From the release:
Templar Brethren are the elite of the VIIth Legion. They are guardians of the Temple of Oaths aboard the Imperial Fists' great fortress-ship the Phalanx and the Legion's most highly accomplished warriors. With their superior skill in battle and the finest weapons at their disposal, they are at the spearhead of the Emperor's Crusade to unify Mankind.
The VIIth Legion's warships are defended from boarding assaults by the Phalanx Warders, warriors selected from amongst the best of the Imperial Fists Breacher squads. Staunch and immovable, they are the last line of defence when attack threatens and the first into the fray when the Legion boards enemy vessels.
These two upgrade sets contain an array of heads, torsos, shields and close combat weapons for you to upgrade a squad of Space Marines to Templar Brethren or Phalanx Warders. These squads can form part of an Imperial Fists Legion army in Horus Heresy games, and their rules can be found in The Horus Heresy Book Three – Extermination and Legiones Astartes – Isstvan Campaign Legions. Each set is a multi-part resin upgrade kit.
They are available to pre-order now and will be despatched from Friday 9th January 2015.
