500 Worlds: Titus – The Battle for Unity Begins
By command of Primarch Roboute Guilliman, the ancient empire of the Five Hundred Worlds shall rise anew in the Imperium's darkest hour. Demetrian Titus, now Captain of the Ultramarines Second Company, fights at the forefront of this war of reclamation. Yet the task that lies before him and his battle-brothers is titanic. Upon the blighted world of Novamagnor, Titus meets a malevolent foe in a battle of wits and will. Can he defeat the monstrous Nekrosor Ammentar, its Destroyer legions, and its stygian shards of the Nightbringer, or will Novamagnor and all its defenders be smothered beneath the shroud of death?

The first of the campaign sets that will conclude the tenth edition of Warhammer 40,000, the narrative of 500 Worlds: Titus sees Captain Demetrian Titus and his forces encounter the insane Necrons of Nekrosor Ammentar during the Ultramarine’s crusade to expand the realm of Ultramar, while the rules allow players to fight a map-based campaign to represent their own attempt to conquer worlds for Roboute Guilliman. The set itself consists of a lore book, a book of Boarding Action rules, a book of campaign rules, a very short book of Detachments, a campaign map and some stickers, all of which are themed around the conquest of Greater Ultramar in general.
The lore book focuses primarily on Captain Titus’ encounter with Nekrosor Ammentar on Novamagnor but also including some information on how the crusade is going in the other warzones of Greater Ultramar. My general dislike of the Ultramarines aside, the lore in the book is reasonably good. While the conflict on Novamagnor does seem strangely lowkey for a planetwide battle, this is probably due to the fact that much of the action is focused on fighting in the close confines of Necron Tomb Complexes due to (possibly due to the rule’s in the set having focusing on the Boarding Action style of gaming) with the wider conflict not getting much focus.
The Dread Incursions book in the set focuses on the Boarding Actions rules with some new, themed Boarding Patrols for Space Marines and Necrons, four Boarding Action campaigns, and twelve new Missions, half of which utilise the Tomb World Boarding Actions terrain set. All these rules seem pretty standard for the Boarding Actions style of play from what I’ve seen. The War on the Vespator Front book, meanwhile, includes rules for a map-based campaign (which seem to be usable both with and without the narrative Crusade rules) along with six themed Missions that can be fought during the campaign. The campaign rules in the book seem quite good, allowing players to build infrastructure on planets they control to gain. There are also suggestions for how to set up battlefields to represent various environments and locations (i.e. Spaceports, Rad Zones, etc.) on a planet along with twists. I quite like these rules as I have always been a fan of such map based campaigns ad these seem reasonably interesting. On the other hand, I very much dislike the fact that each of the environments/locations has a section of tactical advice because I am a firm believer that the choice of such locations should be narrative driven rather tactically driven, and because I feel it is babying players somewhat as it should be up to the players to learn what work best, not simply be told. The book in the set is a very short book of Detachments, with three each for the Space Marines and Necrons. I do like these Detachments as they represent forces that I think should have been in the main Codices for their factions (the Space Marine Orbital Assault Force and the Necron Cryptek Conclave) and/or are nicely themed for the campaign itself (the Ultramarines specific Reclamation Force and the Necron Destroyer focused Cursed Legion). The book could have been improved for including the rules for the models introduced for this campaign though.
The artwork and model photography in the book is a good as usual for a Games Workshop publication. As for the set itself, while the multiple softback books are probably better for gaming I have always hardbacks as I feel they suffer less damage when being lugged around (especially by someone as carless as me) and these books together wouldn’t have been too much weight.
