Six figures, all to create TC-70. FA-4 was originally supposed to be one of the droids, and is now going to come complete with a part for the TC-70.
Personally, I think this is a terrible mix of figures. I don't care about four of the six, and I'll be looking for a complete TC-70 online. It may cost a little more, but it will be better than getting stuck with more crap figures.
