Relive the epic battles of the Horus Heresy!

Remember some of the greatest battles of the Horus Heresy!

For the next two weeks, you will be able to play three different single-player campaigns:
> Unleash the fury of the World Eaters in the Isstvan III campaign > Protect Calth as the Ultramarines in the A Light in the Shadow campaign > Preach Ultramar's doom as the Word Bearers in the Shadow Crusade campaign

This is the last time these campaigns will be available in the regular rotation, so don't miss this chance to beat the final boss and collect the campaigns' exclusive card backs.

For more information, check out the campaign schedule on the official website.
