Hmm, I guess that could be it. The gameplay description seems to fit the bill, as I don't recall any base-building. But I thought it was an original property, or at least, don't think it had Warhammer in the title... Wish I could be more specific. The only vivid image I have of one of these games (I think part 2) are some (horned, I seem to recall) grey monsters who walked on 2 lion-like hind legs, attacking a village.
