Has anybody else noticed this from GW - I couldn't see a thread here. This is the description for the Marine Book:
Altar of War missions provide all the information required to play games inspired by the battlefield tactics of the different Warhammer 40,000 armies. This book contains six brand-new missions which you can use instead of the Eternal War missions in the Warhammer 40,000 rulebook if you or your opponent has a Space Marine army, allowing you to fight the daring lightning assaults, surprise planetfall attacks and heroic last stands of the Emperor’s Space Marines.
Also one for Tau and I think DA up there. Basically a re-hash of battle missions, for 6th ed, at £4.99 a pop.
