Same Scale as Recent Descent 2e? ...also Ardus Ix'Erebus

[Same Scale as Recent Descent 2e? ...also Ardus Ix'Erebus]

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. :-)

[Skirmish mode?]

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?
