I just got an Email from Cryptic describing the May 7th free weekend for returning players and the limited mission demo.
While all that is well and fine, what really caught my attention is this: "There's also new high-end weaponry and a new auto-fire mode for space combat. "
To my knowledge (and mind you, I have only been playing since January), there has always been auto-fire in Space combat. And what new high-end weaponry? I haven't seen any mention of new weapons in the Dev posted engineering reports or the notes when I log in.
IMHO, Cryptic doesn't do a very good job of keeping us players informed...
