Space Marine Codex Preview title image
Genetically altered superhuman warriors created from the flesh of the Emperor Himself, the Space Marines are the greatest defenders of Humanity, standing resolute against the myriad horrors of a hostile galaxy. The Space Marines are superior to normal humans in every respect, thanks to a brutal regime of genetic modification, psycho-conditioning, and a life of strict discipline that only such enhanced warriors can endure. A Space Marine can survive wounds that would kill a normal man thrice over, fight in the harshest conditions imaginable, and rely on his faith in the Immortal Emperor to see him through any situation. Armed with the boltgun, a weapon of divine wrath, and armoured in ancient, artificer-forged suits of power armour, the Space Marines are living embodiments of the Emperor’s Will.

They are the Angels of Death, the fire of the Emperor’s wrath. None can stand before them. With fire and steel, they cleanse the stars of the xeno, purge the galaxy of the wicked, and destroy the enemies of Mankind without mercy.
As you can see from the stat lines below, some things have stayed the same, while others have changed.

Codex: Space Marines is the first of the Warhammer 40,000 Codexes to be redone in the wake of the revised edition of the rules. As such, we’ve lavished quite a bit of attention on it. Inside the book (assuming you make it past the fantastic Karl Kopinski cover!), you’ll find the complete Space Marine army list, which allows you to choose your forces for a tabletop battle. Also included are special rules for selecting unique traits to personalize your own Chapter and give it a flavour beyond the strictures of the Codex Astartes, while maintaining its Codex origins.

The new Whirlwind (click for larger version).
Also included is a wealth of background, with details of the legendary origins of the Space Marines, their illustrious legacy of battle, and their means of recruitment, training, and fighting. You’ll also find guidance on the iconography and heraldry of the Space Marines, together with expert tips on collecting, modeling, and painting a Space Marine army. There are also complete rules and background information for five special characters: Lord Marneus Calgar, Chief Librarian Tigurius, and Chaplain Cassius (all of the Ultramarines Chapter) as well as Captain Lysander of the Imperial Fists and Captain Shrike of the Raven Guard. And as if that wasn’t enough, there are rules for two special Ultramarines units, the Honour Guard of the Chapter Banner and Tyrannic War Veterans!
