If you feel like getting karazy, I had a player make a four-armed changeling, take the ambidextrous quality twice, and pour adept power points into boosting pistols and agility. Could fire 8 times a turn at semi-auto with a dice pool of like 5 each (not so good, but remember every time someone rolls defense their next defence is at -1), or could shoot twice with a dice pool of 20.
He hid the extra arms behind a long duster.
It was cool.
