Oh that hotbed of evil... Ancient Egypt! *Imperial March plays*
Yes, I stole that joke from Linkara.
Anyway, if you'd like to infuse your Chaos Marines with some Ancient Egyptian flavor, you can order the new Dreadnaught and bits from Forge World.
As you can see, the bits come in both "heads and shoulderpads" sets and also separately. I must admit, I do like the look of that Contemptor Dreadnaught and how some of the helmets look.
You can order these now and they'll be shipped out next week.
