Firstly, we did tell you you’d be getting 10 codexes this year, and we can confirm that the next two will be… (dramatic fanfare please):
Codex: Blood Angels and Codex: Dark Angels!
Both of these Chapters are firm fan favourites in the Warhammer 40,000 community, and their new codexes are packed with all sorts of awesome content designed to bring them up to speed with their brethren who adhere more closely to the Codex Astartes. You’ll find Stratagems, Warlord Traits and updated lore, as well rules for including the arsenal of the Primaris Marines in your Blood Angels and Dark Angels armies.
Not to worry, servants of Chaos; 2018 will be kicking off with a new codex for Chaos Daemons, all the better to slay the servants of the Corpse-Emperor (or just anyone who gets in your way) with.
Meanwhile, in the Mortal Realms, something dark is gathering, and the age of hope is drawing to a close. Just look at the new Warhammer Age of Sigmar logo:
Is a dark new age dawning? Did someone just go a bit mad with the Agrax Earthshade? We reckon this new Chaos hero might have something to do with it:
Darkoath Warqueen
If you remember the Darkoath Chieftain from Warhammer Quest Silver Tower, this warrior woman is his boss – although unlike standard bosses, she’s more likely to deal with sub-par performance by ripping someone’s throat out with her teeth instead of giving them a 5 point list of actions to improve on (unless those actions are “tear the hearts from your enemies” and “despoil the realms in the name of the dark gods” and so on).
Meanwhile, in the cursed city of Shadespire, some of Chaos’ more cunning servants rise from the depths:
Spiteclaw’s Swarm sees the skaven scurry, scheme and shiv their way into the ultimate competitive miniatures game. This expansion will contain five new fighters for your games of Warhammer Underworlds: Shadespire, as well as a range of skaven-specific and generic powers and objectives for anyone looking for new ways to steal-steal some shadeglass from the dead-things.
