One of the impressive games this year at GamesDay 2009 was the mega game which comprised a large Imperial city surrounded by a defensive wall. Outside the wall was a bridge.
On the bridge the forces of chaos are moving to attack the Imperial City.
The model builders had used lots and lots of Imperial Bastions and Shrine of the Aquila. For the citybuildings they used the Cities of Death building kits. There were a fair few Valkyries flying about the game too.
