From these pictures: http://icv2.com/gallery/35193/1, the scale looks to be same as Descent. And in the background of this picture: http://icv2.com/gallery/35193/2, it looks like orcs. :-)

I´m trying to make a skirmish game, where both sides choose monsters and heroes. Each side would be 4 heroes and 3 monster groups. Because both sides can choose from the same pool of heroes and monsters, you don´t need points values. I have been looking at DOTA2 for the setup. Are the skirmish mode i Imperial assault "one of" games, or are they played as a part of a campaign?
