Mantic Games have posted photos of their upcoming Revenant Knights including a photo of a work-in-progress paint scheme for one of the knights.
From their announcement:
We are rather excited by the new Mounted Revenant Knights over here at Mantic.
In fact, so excited that we have not been able to stop ourselves from posting a photo of them while still on the painting table!
We feel rather a lot of these might be joining Undead armies everywhere.
