is certainly doing justice to the Imperium of Man's Angels of Death. Although the campaign follows a trio of Ultramarines, which are the mascots for both the Space Marines and the universe as a whole, players have the opportunity to customize their Space Marines.
These customizable Angels of Death can be used in the online PvE missions and the PvP modes, featuring numerous classes and play styles, but for the campaign, players must stick with the Ultramarine squadron of Lieutenant Titus, Chairon, and Gadriel.
The Imperium of Man's Space Marines aren't the only ones that can be customized either, since the PvP mode makes one team play Chaos Space Marines, while the other fights for the Emperor and against heresy. This makes PvP lore friendly, as with every other aspect of the game, and it is clear that the developer cares a great deal about making an accurate representation of the universe.
Still, there is a skin that would be relatable to all miniature painters that would have to break the lore-friendly nature of the game.
As it currently stands, all the skins adhere quite strictly to the pre-established lore of the universe. Players can customize the meshes of their helmets, different pieces of armor, and then choose whatever weapons they want for their loadout, depending on their class choice, of course.
