I've decided to make up a scenario involving the dwarfs defending their stronghold. The idea is to make the orc force larger overall but split them up and give other advantages to the dwarfs...... A heroic last stand for the dwarfs!!!
The dwarf cannot be Broken, they are defending their stronghold to the last dwarf. The whole battle is all about the tales and legends formed after the battle. The Dwarven Stronghold will eventually fall, but how many Orcs have they taken with them? Did this battle cause the orc waaagh to lose it's impetus? (this is inspired from the film 300 )
The Orc army must have at least 5 units on the platform where the dwarf throne is, or kill the dwarf general.
The Orcs start the game with 800 victory points. Each round that they haven't achieved their objective they give the dwarf army 100 victory points. If the orcs haven't achieved any victory conditions by turn 8 the dwarf army wins automatically
The battle will take place inside the dwarf stronghold, deployment for the dwarfs is anywhere in the main room. The dwarfs have a 2 tiered hill in the centre, this represents stairs leading up to a throne. The dwarf statue lets any dwarfs within 12†reroll psychology tests.

There are beer barrels that allows the dwarf player to select one unit per turn within 10cm as “Defender of the Beerâ€, this unit gets to reroll missed hits every turn (dwarfs really hate anyone that tries to take their beer)
There are doors at the end of the tunnels. These can be either be locked and barred, or left open (dwarf players choice) If the doors are barred the dwarf player won't be able to see what units are coming towards him, the orc player uses a coin to represent each unit (a bit like space hulk) Once an orc unit reaches the door they will have to smash through it. All doors have 6 hits, 5+ armour. missile fire from infantry has no effect.
The dwarf general can decide to take some desperate measures that will reduce their victory points, but damage the oncoming hoard....... for example ....... force the young and female dwarfs to fight (similar to helms deep) or destroy a huge statue of a dwarf God to crush everything in the corridor
The orcs get twice as many points. We will experiment with this scenario
I have about 4500 points of orc troops, 60 units (without characters, flyers or artillery) .... with characters about 5500 points of Orcs
Without artillery/flyers/cavalry/chariots i have 2790, 42 units, with no characters
