From the article:
The third instalment in the Broken Realms saga is up for pre-order this weekend, alongside an incredible model for Be’lakor himself. If you haven’t seen it yet, watch this painting guide to get a really good look at the new miniature.
As you’ve come to expect from the series, Broken Realms: Be’lakor improves several armies with updated warscrolls, fresh warscroll battalions, and even a couple of new units.
Naturally, the Daemons of Chaos get a few compelling options, but just take a look at this section of the table of contents – there are loads of interesting entries to ponder.
