Anyone with a Deathwatch book know whether the creatures released for the other two systems, Dark Heresy's Creatures Anathema for example, are compatible with the Deathwatch system?

Without seeing the list of monsters in the Deathwatch Core Rules, I'm hoping that perhaps we might be able to expand our bestiary with some of the other written material.

I don't see why they wouldn't be compatible. The demo adventure clearly shows DW is using the same core d100 mechanics. Probably the worst issue is that the monsters an enemies listed might be too easy.

Unless of course you convert those enemies into hordes... while I know that this doesn't fit the fluff at all, it would mean certain DOOM for a Deathwatch Killteam.... make a horde of Lictors.
