In an effort to cheese out a high-powered game, we've allowed the race builder from SW Deluxe. One of the characters is a 4-armed gunslinger. We're trying to figure out the penalties to shooting 4 guns in a round.

How does ambidextrous affect attacking with more than 2 arms? Does it eliminate the off-hand penalty for all the arms, just one, or something different? Does Two Fisted eliminate the multi-action penalty for all the attacks?
