The group I was in years ago had a house rule to allow quads to "Donky kick"...BOTH rear legs could kick at once! If I recalled, you rolled your piloting against the opponents piloting and if you won, BOTH legs made contact. Then you rolled for both opponent legs separately to see which one got hit. It has the potential for both kicks to hit one leg! Everyone though twice about backstabbing the quads on the table! Imagine...a Scorpion doing 24points ( 55t, 6pts doubled to 12pts, and doubled for the second kick..24pts) of KICK damage to one leg! OUCH!
