Having played through the good side of the WA campaign I decided to do a bit of less linear destruction with the Dark Crusade campaign. I'm currently on campaign turn seven and am already cursing the Guard and their psykers with that damned "Witness your DOOM!".
I'm fielding Space Marines, for goodness sake. They shouldn't be that scared by some little human yelling like that, and they gladly welcome their death in the service of the Emperor as long as they aren't losing their life cheaply.
The first couple of campaign attempts I did months (or more) ago headed off towards the Eldar and along the top of the world. Recently, though, I've headed down and taken out the outer Guard territories. Having just won the territory that gets you a second attack with "Frenzy" I took out the adjoining Chaos territory, but when their defensive rating was only 1 I didn't expect quite so many Defilers!
Now, if only I could defeat these Guardsmen who keep trying to take their territory back. Curse the fact that they are actually two AI players!
