Someone should make a level pack featuring levels from Myth 2 except you played as the Fallen. Not the same levels either. Different ones that you hear about but never play in game. You should be able to play as Soulblighters forces searching for the Summoner or as Shiver attacking White falls. I would do it myself but i suck at scripting so if there is anyone out there who would like to try this let me know.
Couldnt get the link but this one is pretty cool. It gives u dark unitz with different missions as well. Couldnt get the link but i think u can get it if u follow that order above.
Enjoy...

There was a dark campaign on the mill a while back, where you start out fighting as a shade's army against the light, but you fight against sb later on.
