We played the mega-battle scenario. I will report my section, and other may report theirs.
6 players total. For Good, they were deployed Ogre, Ogre, and Salamanders. Evil deployed to face them: Abyssal Dwarves, Empire of Dust, and Twilight Kin.
In my section I deployed:
Reg abyssal Bezerkers
half breed champion
slave orc horde
slave orc reg
special abyssal berserk character
train of 3 heavy angkor mortars
I was facing:
2 Ogre warrior Hordes
Ogre brutes horde
On my left, the Ogres had a scenario rule to outflank, which they did with a giant and thier goblin boomer. I lucked out and had my severely bloodied slave orcs stick around and tie up the giant for a few turns, with some tricky maneuvering.
The center was swept with the cav. Hit hard and broke the ogers even harder. Grog went down first then his hordes one then two at a time. With the mortars taking apart the shooters after a few punishing turns.
By the end of the game, the good armies were down to about 3 units, and I had most of my army left and my allies each had a few units to spare.
