A new edition of Warhammer 40k is upon us. Games Workshop has started taking pre-orders for the new core rulebook and some supplemental materials over in their webshop. There were some limited edition versions, but they all got snatched up pretty quick. But you can still probably ask your LGS to see if they can get them.
From the website:
There is no time for peace. No forgiveness. No respite. There is only war.
The galaxy writhes in the mailed fist of all-consuming conflict. The Imperium of Mankind teeters on the brink of annihilation, beset upon all sides by heretic warlords, daemon-summoning witches and rapacious alien empires. In every star system and upon every planet, fierce battle rages as loyalists, heretics and aliens tear reality itself apart in their war for dominance. Every day the flames rise higher.
This is a more terrible era than ever before, and there is no peace amongst the stars...
A 368-page hardback, this is the essential book for any fan of Warhammer 40,000 – everything you need to know to collect, build, paint and play with Citadel miniatures.
It starts with an overview of the Warhammer 40,000 hobby, covering the four areas of Collect, Built, Paint and Play, including descriptions of open, matched, and narrative play.
