A quick question, does anybody know what fleet boxes and squadrons I'd need to get all the figurines required for the SSD's included in Klingon border and Klingon attack? I haven't decided what race I want to play, but I'm considering Kzinti or Federation and I don't know if I have to purchase squadron boxes in addition to the single large fleet box.
There is nothing in the Squadron box that is not also in the Fleet box. That said, buying a fleet box will not get you everything in Klingon Boarder and Attack. It will get you one or more of: C8, C7, D7, D6 and F5 (and a bunch of shuttles).
Indeed. The existing metal drone and plasma counters should work nicely with the new SL2500 minis. The same could have been said about the existing shuttle though.
