Hey, I'm a GM for a game and I have a player that is looking into the hands free weapon system from Dangerous Covenants. As a GM, I am wondering how this affects combat if he is already dual wielding. I know that normal dual wielding rules would apply for the mounted weapon if he was using it and one other weapon, but he has two blaster pistols, and now one attached with the hands free weapon system, so do I add another purple die for using a third weapon? Thanks for helping out.

No, I wouldn't add 2 difficulty, because it is already more difficult to hit with the second weapon because you need another 2 Advantage (dramatically decreasing the odds of hitting with it) and the first purple represents the added difficulty of coordinating the weapons and I don't think that would stack.

This question has been discussed at length and (IIRC) the three most popular answers are:

1. The increased difficulty for TWC is all you need, regardless of the number of weapons
2. It's an increased difficulty per extra weapon (so three-weapon combat is + )
3. It's + per doubling: so two-weapon is + , three- and four-weapon combat is +
