This is a battle my brothers and I had a while back.
We started with a harpoon jones style 20 minute build time, each of us constructing our fortifications we each chose teams, I took bible heroes: Viking Jesus (with whip and pentecostal flamethrower), John the baptist (with severed head on a stick), The Bad Samaritan, Jonah (With life jacket and harpoon gun) and Michael the jetpack archangel.
My older brother chose a necromancer and his undead horde, and my younger brother picked escaped convicts:
the battle was; The Undead legion (My older brother), Escaped convicts (My younger brother) and Bible Heroes (Me) as I won the initiative, I kicked things off.
With My turret.
Then I moved Michael up:
Firing his own turret, my older brother re-martyrs john:
nothing else of interest happens, and the convicts do nothing worth noting.
I fire the turret...
...to no effect.
So I try attacking with Michael:
An undead sniper and the necromancer combine fire on Michael:
"Every time you hear a cowbell chime, an angel loses his wings":
once again the convicts fail to do anything worth noting.
