Please keep in mind these are pre release models I believe they will be at Games Day but only in limited number.
Terminator armour is the finest protective wargear in the arsenal of the Legiones Astartes. Several different Tactical Dreadnought Armour patterns were developed roughly concurrently by different Forge Worlds during the later decades of the Great Crusade, and most of these, such as the Indomitus, Tartaros and Saturnine patterns, were functionally identical.
The Cataphractii Pattern was amongst the first issued, and suits of this type were even more heavily protected than their contemporaries. Slab-like ceramite pauldrons housed additional shield generators, although this formidable protection came at the cost of the wearer’s speed, and the trade between agility and survivability meant that this pattern was beginning to decline among some Legions at the outbreak of the Heresy.
