A custom battle where both teams (it doesn't have to be two) are made up entirely of heros (with the exception of mabye some horific creatures)
but there are no grouchy hero deductions. All the heros should be heavly armed and(obviously) look awsome.
There should also be titans, heroic units that aren't on anybodys team and have some type of advantage(such as 1d12 skill or mabye 1d10+2)
another fun thing would be to have the winning team go up against the remaining titans, then if the titans win they go after eachother,and the winning unit is blown off the map with a nuke!
atleast thats the way I played it.
(minus the nuke part)
