The only thing we have seen is a pic with the Saucer Separation. There was no information about when it would be coming out. The only thing I have heard is that the cannon will act like a shotgun, with a wide-angle blast, when separated.
I've read a mentioned possibility that if you already own the G-X and the G-R, you can transfer the Separation Console from the G-R over to the Dreadnaught. No further purchase necessary. I've not read a confirmation on this. It would seem to make sense, though.
Unfortunutly i dont have galaxy x or galaxy r so i am hoping that galaxy x is going to get saucer seperetion as promised in cryptic calender this month, and also hopin that would be a part of galaxy pack which is annaunced. Did cryptic said what is in galaxy pack which are they realesing march 29?
