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 Chaos Daemons army, allowing you to wage unholy, genocidal wars in the mortal realm and reap countless souls for the bloodthirsty Chaos Gods.
