Aside from the Visor add (it reduces the recharge time of Shepard's powers), the pack also offers the Capacitor Helmet for faster shield recharge, along with the Inferno Armor, a once pre-order bonus that increases tech and biotic damage and gives you an "edge in negotiations."
If we might play the role of advisor: If you're going to spend $2 on all this advanced armor, negotiations should only take place once the other person is at a severe and permanent disadvantage.
