The new Codex: Space Marines will replace the current Space Marine codex, as well as the other First Founding and Deathwatch codexes – making it an invaluable tome that covers all those elements common across the forces of the Space Marines. A literal Codex Astartes*.
Players using Chapters covered in the last Space Marine codex can carry on using their expansions with the new book – White Scars, Imperial Fists, Iron Hands, Ultramarines, Salamanders, Raven Guard and Black Templars using their codex expansion in the Psychic Awakening series.
For fans of the Dark Angels, Space Wolves, Blood Angels and Deathwatch?
If you have one of these armies, good news – not only do you get a shiny new core codex with loads of new toys to play with, but you also have a new codex supplement on the way. You'll be able to tailor your Space Marines force to fully embody the theme and spirit of their Chapter, and of course, include all their unique units and heroes.
