3 new Droid Assistant cards were offered during the original Kickstarter project as a "Free Expansion". After the Kickstarter, the droids are available to buy for an additional $2. Droids generally help you along the way but with a potential downside if they malfunction! They add an interesting "third character" to any Twin Stars scenario, giving you something else to think about and manage. The series II droids are: - F1D0 - T.R.IX - MANTIS The droid assistant cards are "half-sized" cards, measuring at: 2.5" x 1.75" or 63mm x 44mm.
